1 00:00:03,000 --> 00:00:06,760 Speaker 1: Welcome to Stuff to Blow Your Mind production of iHeartRadio. 2 00:00:12,920 --> 00:00:15,520 Speaker 2: Hey, welcome to Stuff to Blow Your Mind. My name 3 00:00:15,560 --> 00:00:16,120 Speaker 2: is Robert. 4 00:00:15,960 --> 00:00:18,200 Speaker 3: Lamb and I am Joe McCormick. 5 00:00:18,920 --> 00:00:22,200 Speaker 2: In this episode and suffsequent episodes of Stuff to Blow 6 00:00:22,239 --> 00:00:24,319 Speaker 2: Your Mind, we are going to be talking about the 7 00:00:24,360 --> 00:00:27,280 Speaker 2: HeLa Monster. I don't know about you, Joe, but the 8 00:00:27,280 --> 00:00:31,360 Speaker 2: HeLa monster has long been one of my favorite herbs, 9 00:00:31,400 --> 00:00:35,080 Speaker 2: in part clearly because it's the only it was, I think, 10 00:00:35,240 --> 00:00:38,080 Speaker 2: at least growing up, the only natural world animal for 11 00:00:38,200 --> 00:00:42,320 Speaker 2: me officially labeled as a monster. So that's certainly connected 12 00:00:42,360 --> 00:00:45,320 Speaker 2: with me as a kid. I mean, you had Cookie Monster, 13 00:00:45,920 --> 00:00:49,640 Speaker 2: you had the HeLa Monster, So there is a natural 14 00:00:49,640 --> 00:00:52,239 Speaker 2: attraction there, though there to be clear, as we'll be discussing, 15 00:00:52,240 --> 00:00:54,160 Speaker 2: there are plenty of other reasons to love these. 16 00:00:54,040 --> 00:01:00,360 Speaker 3: Creatures definitely attractive and also includes some hidden monstrous It's 17 00:01:00,440 --> 00:01:02,600 Speaker 3: like there are some of the things that might make 18 00:01:02,680 --> 00:01:06,960 Speaker 3: it the most monstrous are things that you wouldn't see 19 00:01:07,000 --> 00:01:09,640 Speaker 3: just looking at a picture of the lizard taken in 20 00:01:09,800 --> 00:01:13,560 Speaker 3: nature and like a National geographic magazine. One of the 21 00:01:13,560 --> 00:01:16,240 Speaker 3: most monstrous things about it, not to skip too far ahead, 22 00:01:16,400 --> 00:01:19,800 Speaker 3: is the way like its bones look or its skull 23 00:01:19,880 --> 00:01:23,720 Speaker 3: looks if you don't have all the cute, kind of fleshy, 24 00:01:24,080 --> 00:01:27,760 Speaker 3: pudgy scan around it that. I'm sure we'll discuss that 25 00:01:27,800 --> 00:01:30,080 Speaker 3: in more detail later, but that was a real shocker 26 00:01:30,160 --> 00:01:32,560 Speaker 3: for me when I in this episode came across a 27 00:01:32,560 --> 00:01:37,039 Speaker 3: CT scan of a HeLa monster head. It's got some 28 00:01:37,080 --> 00:01:37,880 Speaker 3: stuff going on. 29 00:01:38,360 --> 00:01:40,600 Speaker 2: Yeah, yeah, absolutely, it's gonna be fun to get into 30 00:01:40,640 --> 00:01:43,520 Speaker 2: all of that. But just on the surface, you know, 31 00:01:43,840 --> 00:01:48,080 Speaker 2: they don't necessarily look all that monstrous. If you've gotten 32 00:01:48,120 --> 00:01:50,880 Speaker 2: to see one live, then you've probably seen one at 33 00:01:50,880 --> 00:01:53,400 Speaker 2: a zoo, as I have. That's the only place I've 34 00:01:53,400 --> 00:01:56,920 Speaker 2: ever seen live HeLa monsters, and you know, they're generally 35 00:01:56,960 --> 00:01:59,840 Speaker 2: not doing much. They're just letting there. You know, you 36 00:02:00,160 --> 00:02:03,280 Speaker 2: might suspect they are fake because they're they're just resting, 37 00:02:04,040 --> 00:02:06,000 Speaker 2: and they spend a lot of time doing just that, 38 00:02:06,360 --> 00:02:10,600 Speaker 2: but still visually very interesting. They have that signature pink 39 00:02:10,840 --> 00:02:16,200 Speaker 2: slash orange and black colorization, and their general character, at 40 00:02:16,280 --> 00:02:19,320 Speaker 2: least in my opinion, is this is kind of adorable, 41 00:02:19,440 --> 00:02:22,800 Speaker 2: kind of comfy. There's something kind of laid back about 42 00:02:22,840 --> 00:02:23,560 Speaker 2: these lizards. 43 00:02:24,040 --> 00:02:26,560 Speaker 3: I don't recall if I've seen a HeLa monster at 44 00:02:26,560 --> 00:02:30,560 Speaker 3: a zoo, but I've seen another Heloderma lizard, very similar species, 45 00:02:30,600 --> 00:02:32,000 Speaker 3: the Mexican beaded lizard. 46 00:02:32,400 --> 00:02:34,520 Speaker 2: Yeah, I think that one is maybe a little more 47 00:02:34,560 --> 00:02:36,800 Speaker 2: common at zoos. I know the zoo here in Atlanta 48 00:02:36,919 --> 00:02:39,840 Speaker 2: used to have some HeLa monsters and they might have 49 00:02:39,880 --> 00:02:42,160 Speaker 2: them again now. I haven't been in several months. 50 00:02:42,520 --> 00:02:44,680 Speaker 3: When I was recently looking at one of these things 51 00:02:44,760 --> 00:02:46,919 Speaker 3: at a zoo with my daughter, it did not move 52 00:02:46,960 --> 00:02:49,000 Speaker 3: at all. It was just a big kind of a 53 00:02:49,200 --> 00:02:52,079 Speaker 3: just a log in its tank, just sitting there, and 54 00:02:52,440 --> 00:02:54,760 Speaker 3: she didn't seem all that interested in it, maybe because 55 00:02:54,760 --> 00:02:55,400 Speaker 3: it wasn't moving. 56 00:02:55,880 --> 00:02:57,520 Speaker 2: Did you did you not remind her that this is 57 00:02:57,520 --> 00:03:00,920 Speaker 2: a monster? You were looking at a monster, real life monster? 58 00:03:02,080 --> 00:03:02,839 Speaker 3: Didn't break through? 59 00:03:04,280 --> 00:03:07,359 Speaker 2: Well, where do these monsters live where? They are native 60 00:03:07,400 --> 00:03:11,040 Speaker 2: to the southwestern United States and to the northwestern Mexican 61 00:03:11,080 --> 00:03:14,600 Speaker 2: state of Sonora, But they are a rare sighting in 62 00:03:14,639 --> 00:03:20,000 Speaker 2: the wild. So just some personal documentation here. I have 63 00:03:20,120 --> 00:03:23,440 Speaker 2: family uncle and aunt on my wife's side in Arizona. 64 00:03:23,480 --> 00:03:26,880 Speaker 2: They've lived there since nineteen sixty nine, and they've always 65 00:03:26,880 --> 00:03:30,280 Speaker 2: been very active and outdoorsy, you know, going on hikes, 66 00:03:30,680 --> 00:03:34,720 Speaker 2: horseback riding, that sort of thing, you know, always getting 67 00:03:34,760 --> 00:03:37,480 Speaker 2: out there, and they're still getting out there, and I 68 00:03:37,520 --> 00:03:40,840 Speaker 2: had to ask them both about it, texting them earlier 69 00:03:40,840 --> 00:03:43,360 Speaker 2: in the week, and each of them has only ever 70 00:03:43,440 --> 00:03:46,440 Speaker 2: seen a HeLa monster once in the wild. One of 71 00:03:46,440 --> 00:03:49,720 Speaker 2: them saw a HeLa monster on a hiking trail, crossing 72 00:03:49,720 --> 00:03:53,120 Speaker 2: the trail, and then another saw one sunning itself on 73 00:03:53,160 --> 00:03:56,920 Speaker 2: some rocks during a morning horse ride. So I think 74 00:03:57,360 --> 00:03:59,840 Speaker 2: this is just a small sample size, and I'd love 75 00:03:59,880 --> 00:04:03,080 Speaker 2: to hear from any other people who've spent significant amounts 76 00:04:03,080 --> 00:04:05,680 Speaker 2: of time within the range of the Heela Monster. But 77 00:04:06,360 --> 00:04:08,560 Speaker 2: I think it does speak volumes for how secluded these 78 00:04:08,600 --> 00:04:09,480 Speaker 2: creatures tend to be. 79 00:04:09,960 --> 00:04:13,640 Speaker 3: Yeah, you are not likely to see them very often 80 00:04:13,680 --> 00:04:15,960 Speaker 3: for two reasons, I would say. One is that they 81 00:04:16,000 --> 00:04:18,640 Speaker 3: tend to spend the majority of their time hiding in 82 00:04:18,720 --> 00:04:21,800 Speaker 3: burrows or in shelters, and then the other part is 83 00:04:21,800 --> 00:04:24,320 Speaker 3: that when they are out in the open, they have 84 00:04:24,400 --> 00:04:26,920 Speaker 3: these color patterns on them, which actually can help them 85 00:04:26,960 --> 00:04:29,520 Speaker 3: blend in quite well. You might have seen one and 86 00:04:29,600 --> 00:04:30,240 Speaker 3: not seen it. 87 00:04:30,720 --> 00:04:34,640 Speaker 2: Yeah, Yeah, it'd be interesting to discuss their camouflage in 88 00:04:34,680 --> 00:04:38,200 Speaker 2: these episodes because it's kind of My understanding is it's 89 00:04:38,240 --> 00:04:40,520 Speaker 2: kind of both. It's like on one hand, from a distance, 90 00:04:41,080 --> 00:04:44,679 Speaker 2: their colorization can lead can lead to a camouflaged effect, 91 00:04:45,200 --> 00:04:46,880 Speaker 2: make them more difficult to see. But then when you 92 00:04:46,920 --> 00:04:51,120 Speaker 2: get closer, it is more of an alarming visual signature 93 00:04:51,640 --> 00:04:54,240 Speaker 2: warning you you should not mess with this creature for 94 00:04:54,360 --> 00:04:58,440 Speaker 2: reasons that we will discuss now. I've of course been 95 00:04:58,480 --> 00:05:01,200 Speaker 2: visiting Arizona for I think it this point almost twenty years, 96 00:05:01,240 --> 00:05:03,520 Speaker 2: and I've certainly never seen one of these creatures in 97 00:05:03,520 --> 00:05:06,000 Speaker 2: the wild. It's always been in the back of my 98 00:05:06,000 --> 00:05:08,080 Speaker 2: mind It's like a helo monster episode would be good. 99 00:05:08,400 --> 00:05:11,640 Speaker 2: But it was actually on my recent visit to Denver, Colorado, 100 00:05:12,680 --> 00:05:14,720 Speaker 2: that I decided, oh yeah, definitely need to pull the 101 00:05:14,760 --> 00:05:17,919 Speaker 2: trigger on this. This is a place well outside the 102 00:05:17,960 --> 00:05:22,039 Speaker 2: HeLa monsters range. But there was a great volunteer led 103 00:05:22,160 --> 00:05:26,440 Speaker 2: exhibit at the museum titled Nature's Medicine Cabinet, which featured 104 00:05:26,560 --> 00:05:30,520 Speaker 2: helo monsters among various other profile organisms that had either 105 00:05:30,560 --> 00:05:34,520 Speaker 2: been traditionally used in human medicine generally plants as well 106 00:05:34,560 --> 00:05:37,480 Speaker 2: as animals that had come into play had come to 107 00:05:37,480 --> 00:05:41,839 Speaker 2: play a key role due to advancements in peptides. Of note, 108 00:05:41,920 --> 00:05:45,479 Speaker 2: while helas don't naturally live in Denver, the city played 109 00:05:45,520 --> 00:05:48,719 Speaker 2: host to the only known human fatality from a helo 110 00:05:48,800 --> 00:05:51,440 Speaker 2: monster bite in the last century, when a man who 111 00:05:51,560 --> 00:05:54,880 Speaker 2: kept them as pets in Denver suffered a fatal bite. 112 00:05:56,000 --> 00:05:59,480 Speaker 3: I think there is a disputed case of acclaimed HeLa 113 00:05:59,560 --> 00:06:03,000 Speaker 3: monster death from nineteen thirty or so, but one of 114 00:06:03,000 --> 00:06:05,800 Speaker 3: the authors we're going to talk about casts some doubt 115 00:06:05,880 --> 00:06:08,240 Speaker 3: on the veracity of that one. But yeah, I also 116 00:06:08,279 --> 00:06:11,240 Speaker 3: read about the same case in Colorado. But as we 117 00:06:11,279 --> 00:06:14,600 Speaker 3: will discuss later on, while the venom of the heel 118 00:06:14,680 --> 00:06:19,560 Speaker 3: monster is quite a cocktail, it is incredibly potent. It 119 00:06:20,360 --> 00:06:22,919 Speaker 3: There are a lot of documented helo monster bites and 120 00:06:23,040 --> 00:06:27,120 Speaker 3: almost none of them have resulted in death, So very potent, 121 00:06:28,000 --> 00:06:31,680 Speaker 3: something you absolutely do not want to experience for reasons 122 00:06:31,680 --> 00:06:34,560 Speaker 3: that we will talk about, but usually not fatal. 123 00:06:34,920 --> 00:06:37,960 Speaker 2: Yeah, and to be clear, we'll drive this again and 124 00:06:37,960 --> 00:06:40,000 Speaker 2: again as well. This is not a creature you need 125 00:06:40,040 --> 00:06:44,000 Speaker 2: to be afraid of. Your chances of an encountering one 126 00:06:44,000 --> 00:06:47,080 Speaker 2: in the wild are so rare. Really, the people who 127 00:06:47,279 --> 00:06:50,800 Speaker 2: have been bitten by them are generally actively handling them. 128 00:06:50,839 --> 00:06:53,120 Speaker 2: They have sought them out, or they have them as pets, 129 00:06:54,200 --> 00:06:56,080 Speaker 2: and so that's just not going to happen. If you 130 00:06:56,160 --> 00:06:59,720 Speaker 2: were if you were doing anything outdoors or indoors within 131 00:06:59,760 --> 00:07:02,800 Speaker 2: thee of the HeLa monster. There's a long list of 132 00:07:02,839 --> 00:07:04,880 Speaker 2: things that are more dangerous to you ahead of that. 133 00:07:05,320 --> 00:07:07,760 Speaker 3: Yeah, that's the I was reading the exact same thing. 134 00:07:07,800 --> 00:07:11,040 Speaker 3: It's not like you might read about rattlesnake bites, where 135 00:07:11,080 --> 00:07:13,360 Speaker 3: sometimes it's just a chance encounter. You step in the 136 00:07:13,400 --> 00:07:16,240 Speaker 3: wrong place, so you accidentally come across one and there's 137 00:07:16,240 --> 00:07:20,520 Speaker 3: a strike. With the heel monster, it is almost entirely 138 00:07:20,560 --> 00:07:24,040 Speaker 3: a case of people intentionally messing with these animals that 139 00:07:24,160 --> 00:07:26,760 Speaker 3: results in bites. It's not one where they're going to 140 00:07:26,800 --> 00:07:27,800 Speaker 3: sneak up and get you. 141 00:07:28,280 --> 00:07:31,960 Speaker 2: Yeah. Absolutely. But before we dive in a little bit 142 00:07:32,000 --> 00:07:33,680 Speaker 2: more here, I just want to mention a couple of 143 00:07:33,680 --> 00:07:37,320 Speaker 2: sources that we were referring to here. I guess the 144 00:07:37,320 --> 00:07:40,360 Speaker 2: big one is Biology of HeLa Monsters and Beaded Lizards 145 00:07:40,680 --> 00:07:44,320 Speaker 2: by Daniel D. Beck, University of California Press. 146 00:07:45,120 --> 00:07:46,400 Speaker 3: Yeah. I looked up Daniel D. 147 00:07:46,480 --> 00:07:46,680 Speaker 2: Beck. 148 00:07:46,720 --> 00:07:49,280 Speaker 3: He's a biology professor. I think he's retired now, but 149 00:07:49,320 --> 00:07:52,000 Speaker 3: he was affiliated with Central Washington University. 150 00:07:52,400 --> 00:07:55,240 Speaker 2: Yeah, And then text that I was at more general 151 00:07:56,120 --> 00:07:58,600 Speaker 2: herb text that I've been looking at as a slightly 152 00:07:58,640 --> 00:08:01,360 Speaker 2: older piece from Age published nineteen ninety eight, though I 153 00:08:01,360 --> 00:08:03,680 Speaker 2: think the addition I have is a more revised edition 154 00:08:03,720 --> 00:08:06,680 Speaker 2: from like two thousand and five. It is Encyclopedia of 155 00:08:06,720 --> 00:08:10,840 Speaker 2: Reptiles and Amphibian second Edition by Harold G. Kauger and 156 00:08:10,920 --> 00:08:14,440 Speaker 2: Richard G. Zwiffel. Also a nice text. And we're also 157 00:08:14,440 --> 00:08:17,800 Speaker 2: going to refer to some more recent studies concerning the 158 00:08:17,840 --> 00:08:20,680 Speaker 2: HeLa Monster, because one of the amazing things that I've 159 00:08:20,680 --> 00:08:23,040 Speaker 2: seen pointed out is that despite the fact that the 160 00:08:23,040 --> 00:08:26,760 Speaker 2: HeLa Monster is pretty famous, it is like a sports mascot, 161 00:08:26,840 --> 00:08:30,360 Speaker 2: and you know, and everybody knows about it. It's shown 162 00:08:30,440 --> 00:08:33,719 Speaker 2: up in numerous films, sometimes at least once, well more 163 00:08:33,760 --> 00:08:38,240 Speaker 2: than once in the starring role, not necessarily Oscar worthy pictures. 164 00:08:38,280 --> 00:08:40,839 Speaker 2: But you can't blame the Helo Monster. That's more the 165 00:08:41,120 --> 00:08:46,840 Speaker 2: agents of fault forgetting the Helo Monster these gigs. But movies, Yeah, 166 00:08:46,840 --> 00:08:48,800 Speaker 2: that's sort of they and some more recent films in 167 00:08:48,880 --> 00:08:52,280 Speaker 2: that sort of vein. But yeah, despite it being such 168 00:08:52,280 --> 00:08:55,719 Speaker 2: a well known creature, there are certain aspects of its 169 00:08:55,760 --> 00:08:59,760 Speaker 2: biology that are as yet not fully understood or certainly 170 00:09:00,040 --> 00:09:03,560 Speaker 2: where we've been catching up in recent years figuring exactly 171 00:09:03,600 --> 00:09:16,520 Speaker 2: how they work. All right, Well, let's dive into it 172 00:09:16,559 --> 00:09:20,520 Speaker 2: a bit more. What sort of lizard is the HeLa monster. 173 00:09:20,760 --> 00:09:24,360 Speaker 2: Let's narrow it down. They're technically beaded lizards of the 174 00:09:24,400 --> 00:09:30,000 Speaker 2: family helo dermat today and its sole genus Heloderma. It's 175 00:09:30,040 --> 00:09:33,560 Speaker 2: a small family, small genus with previously, I believe only 176 00:09:33,640 --> 00:09:38,240 Speaker 2: five recognized extant species native to the Americas, including the 177 00:09:38,240 --> 00:09:43,360 Speaker 2: HeLa monster, the Mexican beaded lizard, and the Guatemalan beaded lizard. Historically, 178 00:09:43,400 --> 00:09:46,640 Speaker 2: we thought there were only two Mexican beated lizard and 179 00:09:46,679 --> 00:09:49,520 Speaker 2: the Helo monster. So many older sources are going to 180 00:09:49,760 --> 00:09:53,600 Speaker 2: reflect that all of them are venomous, the only venomous 181 00:09:53,600 --> 00:09:56,800 Speaker 2: extant lizards, and the Helo monster is generally singled out 182 00:09:56,840 --> 00:09:59,439 Speaker 2: as being the only literal venomous lizard native to the 183 00:09:59,520 --> 00:10:00,000 Speaker 2: United States. 184 00:10:00,760 --> 00:10:02,640 Speaker 3: I had a bit of confusion when I was reading 185 00:10:02,679 --> 00:10:06,000 Speaker 3: about this, because several sources I was reading refer to 186 00:10:06,040 --> 00:10:09,760 Speaker 3: the Heloderma lizards, the small family of species, as the 187 00:10:09,800 --> 00:10:14,200 Speaker 3: only venomous lizards on Earth, and yet there are some 188 00:10:14,400 --> 00:10:18,640 Speaker 3: other lizard species I think, mostly monitor lizards like the 189 00:10:18,679 --> 00:10:22,480 Speaker 3: Komodo dragon, that also do have some kind of venom. 190 00:10:22,520 --> 00:10:27,200 Speaker 3: I think this might come down to distinctions that specialists 191 00:10:27,240 --> 00:10:29,600 Speaker 3: make about, like how the venom is delivered and what 192 00:10:29,640 --> 00:10:33,200 Speaker 3: its primary function is. So there is some other venom 193 00:10:33,320 --> 00:10:37,440 Speaker 3: in lizards out there, but these in some special way 194 00:10:37,559 --> 00:10:41,239 Speaker 3: are like the most primarily venomous lizards. 195 00:10:41,760 --> 00:10:44,560 Speaker 2: Yes, absolutely, yeah, yeah, to be clear, Yeah, the monitor 196 00:10:44,600 --> 00:10:48,719 Speaker 2: lizards of Africa, Asia, Indonesia, and Australia are also venomous 197 00:10:48,760 --> 00:10:50,920 Speaker 2: and thought to be thought to be closely related in 198 00:10:50,960 --> 00:10:53,680 Speaker 2: the grand scheme of things here. And this does include 199 00:10:53,720 --> 00:10:58,319 Speaker 2: the mighty komodo dragons of Indonesia, which have an anticoagulant 200 00:10:58,400 --> 00:11:02,760 Speaker 2: and I believe neurotoxic venom, but mostly is noted for 201 00:11:02,920 --> 00:11:07,160 Speaker 2: its blood thinning properties. So, like you know, a komodo 202 00:11:07,240 --> 00:11:11,280 Speaker 2: dragon bites its prey, it inflicts a pretty dire wound, 203 00:11:11,400 --> 00:11:13,720 Speaker 2: and a wound that is also going to drain out 204 00:11:13,760 --> 00:11:14,440 Speaker 2: a lot faster. 205 00:11:15,160 --> 00:11:17,640 Speaker 3: Years ago, I remember us talking about this idea that 206 00:11:17,720 --> 00:11:19,480 Speaker 3: had been floating around for a long time that the 207 00:11:19,520 --> 00:11:27,160 Speaker 3: komodo dragon in particular had weaponized pathogenic bacteria in its 208 00:11:27,200 --> 00:11:29,520 Speaker 3: mouth so that it would like bite its prey. I 209 00:11:29,520 --> 00:11:31,320 Speaker 3: guess the idea is it would bite its prey and 210 00:11:31,360 --> 00:11:34,760 Speaker 3: this would cause an infection and then later the komodo 211 00:11:34,880 --> 00:11:38,520 Speaker 3: dragon could take advantage of this and take down the prey. 212 00:11:39,640 --> 00:11:42,280 Speaker 3: This apparently used to be a pretty popular theory, but 213 00:11:42,400 --> 00:11:45,040 Speaker 3: recent research has turned against it. So I was reading 214 00:11:45,080 --> 00:11:49,880 Speaker 3: some articles about this, quoting a toxicologist named Brian Frye 215 00:11:50,000 --> 00:11:53,360 Speaker 3: at the University of Queensland who talks about how actually 216 00:11:53,440 --> 00:11:57,040 Speaker 3: komodo dragon mouths are not especially they don't have a 217 00:11:57,120 --> 00:12:00,680 Speaker 3: specially dangerous bacteria in them. In fact, they're relatively clean 218 00:12:00,840 --> 00:12:04,160 Speaker 3: as far as animal mouths go. Kimodo dragons spend a 219 00:12:04,160 --> 00:12:07,160 Speaker 3: lot of time cleaning their mouths, kind of licking and 220 00:12:07,200 --> 00:12:10,360 Speaker 3: smacking their lips and rubbing their heads on things in 221 00:12:10,360 --> 00:12:13,440 Speaker 3: the environment, like rubbing their mouths against leaves to try 222 00:12:13,440 --> 00:12:15,720 Speaker 3: to clean them off after meals. So you have this 223 00:12:15,840 --> 00:12:18,680 Speaker 3: old idea of the kimodo dragons with rotting meat in 224 00:12:18,720 --> 00:12:21,400 Speaker 3: their teeth or something, and this kind host bacteria that 225 00:12:21,480 --> 00:12:24,480 Speaker 3: will infect the prey animal after it gets a bite 226 00:12:24,520 --> 00:12:27,839 Speaker 3: from the komodo dragon. That seems to be not really 227 00:12:27,840 --> 00:12:31,280 Speaker 3: the case. Their mouths are not really different from the 228 00:12:31,320 --> 00:12:34,480 Speaker 3: mouths of other carnivores, and fry says that they just 229 00:12:34,520 --> 00:12:38,040 Speaker 3: don't have enough bacteria in their mouths to really harm 230 00:12:38,080 --> 00:12:40,839 Speaker 3: an injured animal anymore than you would expect a bite 231 00:12:40,840 --> 00:12:41,880 Speaker 3: of any animal too. 232 00:12:42,440 --> 00:12:46,640 Speaker 2: Yeah. Yeah, and this makes sense on several grounds. For starters, 233 00:12:46,760 --> 00:12:49,719 Speaker 2: we know that while komodo dragons are voracious eaters, they 234 00:12:49,720 --> 00:12:53,000 Speaker 2: consume something like all but twelve percent of a body, 235 00:12:54,000 --> 00:12:58,600 Speaker 2: tearing it apart with their strong foe loombs and serrated teeth, which, 236 00:12:58,640 --> 00:13:02,360 Speaker 2: by the way, sets monitor lizards in general apart from 237 00:13:02,440 --> 00:13:06,520 Speaker 2: most reptiles, aside from I believe sea turtles in that 238 00:13:06,559 --> 00:13:09,480 Speaker 2: they're not swallowing prey whole. They're you know, tearing it up. 239 00:13:10,880 --> 00:13:14,520 Speaker 2: They but but yeah, they're they're in their own way fastidious. 240 00:13:14,760 --> 00:13:17,600 Speaker 2: They take care to sling out the contents of intestines 241 00:13:17,600 --> 00:13:21,679 Speaker 2: before they eat them, and their small young avoid cannibalization 242 00:13:21,880 --> 00:13:25,640 Speaker 2: by their gigantic elders, in part by rolling around in 243 00:13:25,720 --> 00:13:26,320 Speaker 2: such filth. 244 00:13:27,720 --> 00:13:31,840 Speaker 3: Interesting. Yeah, so that they're too smelly to eat, I guess, yeah. 245 00:13:31,679 --> 00:13:34,200 Speaker 2: Yeah, that in common. They also like tend to stick 246 00:13:34,240 --> 00:13:36,560 Speaker 2: to the trees, so yeah, they're they're too young to 247 00:13:36,600 --> 00:13:38,960 Speaker 2: get along with the big kimodos. They stay up in 248 00:13:39,000 --> 00:13:41,560 Speaker 2: the trees. As they grow in size, they come down. 249 00:13:41,679 --> 00:13:45,000 Speaker 2: But kmodo dragons grow throughout their lives, like you know 250 00:13:45,040 --> 00:13:48,280 Speaker 2: a lot of reptile species that we've discussed. So there's 251 00:13:49,559 --> 00:13:51,600 Speaker 2: there's still going to be a mismatch, and you're gonna 252 00:13:51,600 --> 00:13:55,280 Speaker 2: have these situations where komodo drag the large ones have 253 00:13:55,679 --> 00:14:00,480 Speaker 2: taken down prey and or are scavenging prey, and so 254 00:14:00,520 --> 00:14:03,440 Speaker 2: there's some sort of large, smelly feast to be had. 255 00:14:03,840 --> 00:14:06,160 Speaker 2: The big dragons are going to have primary access to that. 256 00:14:06,440 --> 00:14:08,920 Speaker 2: The younger dragons, the ones that are there, they're big 257 00:14:09,040 --> 00:14:11,160 Speaker 2: enough to come down from the trees, but they're not 258 00:14:11,160 --> 00:14:13,680 Speaker 2: big enough to get in on the buffet. They're going 259 00:14:13,760 --> 00:14:18,160 Speaker 2: to go around in this circle, this kind of uh, 260 00:14:18,360 --> 00:14:21,920 Speaker 2: this circle of that's like a nervous circle that's going 261 00:14:21,920 --> 00:14:25,160 Speaker 2: around the feeding area, an appeasement circle, I believe it's 262 00:14:25,200 --> 00:14:27,840 Speaker 2: sometimes referred to as where they're just kind of hanging 263 00:14:27,920 --> 00:14:30,640 Speaker 2: around making it clear that they are not contesting the 264 00:14:30,760 --> 00:14:32,760 Speaker 2: kill at all, They are not attempting to get in, 265 00:14:33,080 --> 00:14:36,520 Speaker 2: but they are ready to do clean up after the 266 00:14:36,800 --> 00:14:40,280 Speaker 2: main meal has taken place. So, yeah, kimodos in and 267 00:14:40,320 --> 00:14:45,120 Speaker 2: of themselves instant endlessly fascinating as well, you know, enormous 268 00:14:45,400 --> 00:14:49,520 Speaker 2: predatory lizards and yeah, so I guess the other thing 269 00:14:49,560 --> 00:14:52,560 Speaker 2: thinking about this whole this this again this idea that 270 00:14:52,600 --> 00:14:56,880 Speaker 2: there was harmful bacteria in their saliva, which you see 271 00:14:56,880 --> 00:14:59,000 Speaker 2: that in the older sources and even in not so 272 00:14:59,120 --> 00:15:01,680 Speaker 2: old sources. They so kind of you see, kind of 273 00:15:01,680 --> 00:15:05,600 Speaker 2: like a halfway holding onto that concept where they're saying, Okay, 274 00:15:05,640 --> 00:15:08,280 Speaker 2: there's a toxin, there's a venom in play, but also 275 00:15:08,600 --> 00:15:11,200 Speaker 2: the bacteria. But you know, when you look at the 276 00:15:11,200 --> 00:15:14,480 Speaker 2: full equation of what they have, their strength, their teeth, 277 00:15:14,520 --> 00:15:19,200 Speaker 2: their anticoagulant, venom, they certainly don't need a bacterially potent 278 00:15:19,240 --> 00:15:21,880 Speaker 2: bite to get the job done. I suspect some of 279 00:15:21,920 --> 00:15:24,840 Speaker 2: this also goes back to prior interpretations of the Komodo 280 00:15:24,960 --> 00:15:29,880 Speaker 2: dragon as being primarily scavengers. In part this may have 281 00:15:29,920 --> 00:15:31,440 Speaker 2: been due to the fact that you would see them, 282 00:15:31,520 --> 00:15:36,560 Speaker 2: you know, all hanging out around this rotting kill. But 283 00:15:37,120 --> 00:15:40,000 Speaker 2: nowadays we know that they are very capable hunters, bringing 284 00:15:40,000 --> 00:15:43,000 Speaker 2: down things like water buffaloes and deer, and they are 285 00:15:43,000 --> 00:15:45,240 Speaker 2: in fact apex predators in their environments. 286 00:15:45,480 --> 00:15:48,920 Speaker 3: Yeah, so attacking live prey, going after it, taking it 287 00:15:48,960 --> 00:15:52,920 Speaker 3: down with strength, with jaws, all that stuff. Yeah, and 288 00:15:53,080 --> 00:15:54,560 Speaker 3: the help of some venom as well. 289 00:15:54,800 --> 00:15:56,640 Speaker 2: Yeah, Yeah, I think the idea is, yeah, they get 290 00:15:56,680 --> 00:15:59,160 Speaker 2: a really good bite in. If the prey makes it 291 00:15:59,280 --> 00:16:01,360 Speaker 2: away from them, they're not going to make it too 292 00:16:01,400 --> 00:16:03,400 Speaker 2: far and they're going to succumb to those injuries. 293 00:16:04,120 --> 00:16:06,400 Speaker 3: But again to emphasize, based on what I was reading, 294 00:16:06,440 --> 00:16:08,360 Speaker 3: it seems like komodo dragons are not going to be 295 00:16:08,360 --> 00:16:12,520 Speaker 3: as dependent on their venom for a hunting and predation 296 00:16:12,840 --> 00:16:15,240 Speaker 3: as like most venomous snakes are. 297 00:16:15,920 --> 00:16:18,080 Speaker 2: Yeah, like you can think of a venomous snake almost 298 00:16:18,080 --> 00:16:20,760 Speaker 2: as a sniper, whereas the komodo dragon is more like 299 00:16:20,880 --> 00:16:26,560 Speaker 2: artillery I guess, and some similar interpretations are going to 300 00:16:28,040 --> 00:16:30,400 Speaker 2: transition into and I'm certainly going to apply to what 301 00:16:30,400 --> 00:16:32,120 Speaker 2: we're going to be talking about with the HeLa Monster. 302 00:16:33,040 --> 00:16:35,520 Speaker 2: So coming back to the Helo monster, what does this 303 00:16:35,640 --> 00:16:39,840 Speaker 2: name mean? You know, I think, going back to childhood interpretations, 304 00:16:40,160 --> 00:16:43,320 Speaker 2: this is you know, we encounter the word HeLa. It 305 00:16:43,400 --> 00:16:45,760 Speaker 2: is spelled g i l a. This leads to a 306 00:16:45,840 --> 00:16:49,960 Speaker 2: number of early mispronunciations as we talk about the Gila monster. Perhaps, 307 00:16:50,600 --> 00:16:52,960 Speaker 2: but it is HeLa and it is named for the 308 00:16:53,000 --> 00:16:56,280 Speaker 2: HeLa River basin of New Mexico and Arizona, where it 309 00:16:56,320 --> 00:17:01,520 Speaker 2: was once plentiful. The scientific name is Heloderma suspectum, which 310 00:17:01,560 --> 00:17:06,000 Speaker 2: translates to suspicious wart skin, with the suspart coming from 311 00:17:06,080 --> 00:17:11,080 Speaker 2: nineteenth century paleontologist and biologist Edward Drinker Cope. Some of 312 00:17:11,080 --> 00:17:13,280 Speaker 2: you may remember that name. He was one of the 313 00:17:13,359 --> 00:17:16,439 Speaker 2: key individuals in the paleontologist Bone Wars. 314 00:17:16,800 --> 00:17:21,000 Speaker 3: Yeah. So, according to that book by Beck, the reason 315 00:17:21,800 --> 00:17:26,359 Speaker 3: that these lizards were suspicious to Cope was that Cope 316 00:17:26,520 --> 00:17:30,879 Speaker 3: suspected that they were venomous but couldn't be sure. And 317 00:17:30,920 --> 00:17:34,160 Speaker 3: this was actually an unsettled issue for like hundreds of years, 318 00:17:34,280 --> 00:17:38,000 Speaker 3: the different naturalists making opposing claims about whether HeLa monsters 319 00:17:38,000 --> 00:17:42,119 Speaker 3: were venomous or not. It wasn't until around the nineteen twenties, 320 00:17:42,160 --> 00:17:45,760 Speaker 3: by Beck's reckoning, that enough evidence had been marshaled to 321 00:17:45,800 --> 00:17:49,440 Speaker 3: convince basically everybody in the field that they were truly venomous, 322 00:17:49,680 --> 00:17:52,160 Speaker 3: and yet the species name stuck. So I think it's 323 00:17:52,160 --> 00:17:57,040 Speaker 3: funny that HeLa monsters are in their scientific name forever suspected, 324 00:17:57,160 --> 00:18:01,640 Speaker 3: even though they are one hundred percent guilty, poor critters. 325 00:18:02,320 --> 00:18:04,320 Speaker 2: I think it is telling that this was such this 326 00:18:04,440 --> 00:18:07,600 Speaker 2: remains such an open question because, as we'll discuss, anyone 327 00:18:07,600 --> 00:18:11,000 Speaker 2: who has ever actually been bitten by a HeLa monster. 328 00:18:11,520 --> 00:18:15,000 Speaker 2: There's no doubt concerning this. Well. 329 00:18:15,080 --> 00:18:18,080 Speaker 3: Beck tells a funny story where one of the guys 330 00:18:18,080 --> 00:18:21,600 Speaker 3: who was arguing, no, they're not venomous, got a bite 331 00:18:21,640 --> 00:18:24,000 Speaker 3: from a HeLa monster and apparently it wasn't that bad. 332 00:18:24,040 --> 00:18:26,000 Speaker 3: So maybe it was just a dry bite. I don't know, 333 00:18:26,320 --> 00:18:31,120 Speaker 3: Like we'll talk later about the venomation mechanism, So maybe 334 00:18:31,160 --> 00:18:34,000 Speaker 3: this guy got a quick little nip without much venom, 335 00:18:34,160 --> 00:18:37,199 Speaker 3: you know, mashed in or something. Yeah, it was like, 336 00:18:37,720 --> 00:18:41,120 Speaker 3: no big deal. I don't think they're venomous. I would 337 00:18:41,160 --> 00:18:44,240 Speaker 3: love to compare that to other accounts of bites from 338 00:18:44,280 --> 00:18:48,920 Speaker 3: these things, which are epic to read. But I wanted 339 00:18:48,920 --> 00:18:51,159 Speaker 3: to note another interesting thing about their scientific names. So 340 00:18:51,200 --> 00:18:55,200 Speaker 3: the genus name again is a Heloderma. The species name 341 00:18:55,200 --> 00:18:58,400 Speaker 3: suspect them. Suspect them because they were suspected of being venomous, 342 00:18:58,400 --> 00:19:02,080 Speaker 3: and they were. But the the genus name can be interpreted, 343 00:19:02,119 --> 00:19:05,600 Speaker 3: like you said, as wardy skin, though more literally it 344 00:19:05,640 --> 00:19:10,040 Speaker 3: comes from the Greek that means skin of nails or 345 00:19:10,119 --> 00:19:14,479 Speaker 3: skin of studs. This will relate to a biological feature 346 00:19:14,520 --> 00:19:17,719 Speaker 3: we'll talk about in a minute called the osteoderms, but 347 00:19:17,840 --> 00:19:21,159 Speaker 3: so heloderma. The derma of course means skin, but the 348 00:19:21,200 --> 00:19:24,560 Speaker 3: helopart comes from the Greek word helos, referring to a 349 00:19:24,720 --> 00:19:28,040 Speaker 3: nail or a stud, or more specifically, the flat head 350 00:19:28,040 --> 00:19:31,440 Speaker 3: of a nail, So these are nail skin. There are 351 00:19:31,640 --> 00:19:34,640 Speaker 3: pin head lizards in a way. I'm thinking of Doug Bradley. 352 00:19:35,119 --> 00:19:38,840 Speaker 2: Yeah, yeah, I think pinhead lizard is a nice nickname 353 00:19:39,280 --> 00:19:43,280 Speaker 2: for the HeLa monster. Yeah, because warts, they're not really warts. 354 00:19:44,440 --> 00:19:46,959 Speaker 2: Beads I think is a better physical description of what 355 00:19:46,960 --> 00:19:49,960 Speaker 2: we're looking at. These, as you mentioned, are in fact 356 00:19:50,000 --> 00:19:54,399 Speaker 2: bony osteoderms that do indeed provide an armor layer for 357 00:19:54,440 --> 00:19:58,000 Speaker 2: the HeLa monster as well as their beaded and monitor 358 00:19:58,080 --> 00:20:01,560 Speaker 2: lizard can. I frequently see it compared to various medieval 359 00:20:01,640 --> 00:20:04,320 Speaker 2: armors such as chain mail, you know, pretty obvious thing 360 00:20:04,400 --> 00:20:07,000 Speaker 2: to compare it to, though this can be confusing as 361 00:20:07,200 --> 00:20:11,439 Speaker 2: osteoderms do not overlap. I've read the lizards also have 362 00:20:11,600 --> 00:20:15,919 Speaker 2: scales atop these osteoderms as well, and osteoderms can fuse 363 00:20:16,040 --> 00:20:19,640 Speaker 2: with the skeleton and with the Helo monster, they specifically 364 00:20:19,800 --> 00:20:24,240 Speaker 2: fuse with their skulls, creating just a very memorable skull 365 00:20:24,320 --> 00:20:26,240 Speaker 2: if you were an easy skull. Yeah, if you were 366 00:20:26,240 --> 00:20:28,960 Speaker 2: not behind the wheel of a car, or I don't know, 367 00:20:29,840 --> 00:20:31,440 Speaker 2: non jury do it. I don't know whatever you're doing. 368 00:20:31,520 --> 00:20:35,200 Speaker 2: Or you shouldn't look at your phone or your computer screen. 369 00:20:35,520 --> 00:20:37,600 Speaker 2: If you are able, look them up. Look up some 370 00:20:37,720 --> 00:20:42,000 Speaker 2: images of Helo monster skulls alongside Helo monster fleshed heads, 371 00:20:42,480 --> 00:20:46,080 Speaker 2: and it's pretty pretty memorable, and I would say pretty metal. 372 00:20:46,560 --> 00:20:48,560 Speaker 3: Another thing, if you get a chance to look up, 373 00:20:48,760 --> 00:20:52,080 Speaker 3: is a picture of a CT scan of a HeLa 374 00:20:52,160 --> 00:20:54,440 Speaker 3: monster head, which I came across in a paper that 375 00:20:54,840 --> 00:20:57,000 Speaker 3: I think we were both looking out for this episode 376 00:20:57,040 --> 00:21:01,440 Speaker 3: by Gordon W. S Hewitt at all. Lead author is Shwett. 377 00:21:02,359 --> 00:21:04,560 Speaker 3: So this is a paper about I think it's mainly 378 00:21:04,600 --> 00:21:08,639 Speaker 3: about female female aggression fighting between Heela monsters. But it 379 00:21:08,760 --> 00:21:10,680 Speaker 3: just throws in in the middle of the paper here 380 00:21:10,680 --> 00:21:13,960 Speaker 3: are some CT scans of Helo monster heads. It gives 381 00:21:14,040 --> 00:21:17,520 Speaker 3: you top view, bottom view, lateral view. Especially the lateral 382 00:21:17,600 --> 00:21:20,720 Speaker 3: view of the head. It doesn't look real. It looks 383 00:21:20,760 --> 00:21:24,520 Speaker 3: like an illustration of a dragon. Because so you have 384 00:21:24,640 --> 00:21:27,000 Speaker 3: these osteoderms, like we've been talking about, these kind of 385 00:21:27,400 --> 00:21:32,280 Speaker 3: bulbous little beads, these wardy shaped, little bony patches covering 386 00:21:32,320 --> 00:21:35,920 Speaker 3: the entire head, and then also a little bit less 387 00:21:35,960 --> 00:21:39,320 Speaker 3: densely grouped but also covering the neck. And then the 388 00:21:39,520 --> 00:21:42,520 Speaker 3: head just terminates in these empty eye sockets and these 389 00:21:42,640 --> 00:21:45,840 Speaker 3: teeth that look like something out of a fantasy. They're 390 00:21:46,040 --> 00:21:51,760 Speaker 3: a horrible, just long, spiny, spear tip looking teeth that 391 00:21:52,600 --> 00:21:54,719 Speaker 3: look more like a drawing than like nature. 392 00:21:55,320 --> 00:21:57,720 Speaker 2: It really, if you didn't know what a helo monster's 393 00:21:57,720 --> 00:22:00,960 Speaker 2: skull looks like, you might suspect that this is a 394 00:22:01,000 --> 00:22:05,280 Speaker 2: Halloween decoration that you buy at lows in like late September. Yeah. 395 00:22:05,320 --> 00:22:07,919 Speaker 3: Yeah, it looks like dragons from movies. It looks like 396 00:22:08,119 --> 00:22:10,320 Speaker 3: one of the things from Game of Thrones. Yeah, like 397 00:22:10,359 --> 00:22:12,800 Speaker 3: a dragon the head with ridiculous teeth. 398 00:22:13,240 --> 00:22:19,080 Speaker 2: Yeah yeah, absolutely gnarly. And again it's an interesting juxtaposition. 399 00:22:19,800 --> 00:22:23,199 Speaker 2: When you look at a fleshed, fully fleshed HeLa monster, 400 00:22:24,320 --> 00:22:26,800 Speaker 2: I would say, you know, with that signature black and 401 00:22:27,040 --> 00:22:29,920 Speaker 2: pink orange color scheme, I tend to think they look 402 00:22:30,119 --> 00:22:32,359 Speaker 2: kind of sweet, you know, a little bit lazy, a 403 00:22:32,359 --> 00:22:36,840 Speaker 2: little bit silly. Yeah, totally not the same sinister vibes. 404 00:22:37,440 --> 00:22:40,520 Speaker 3: They often have sweet looking eyes. They're just looking at 405 00:22:40,560 --> 00:22:41,800 Speaker 3: you like, hey, what's up. 406 00:22:43,520 --> 00:22:48,520 Speaker 2: Yeah. Absolutely, though to be clear, do not attempt to 407 00:22:48,560 --> 00:22:51,040 Speaker 2: love them in a physical manner. No love from a farm. 408 00:22:51,280 --> 00:23:01,480 Speaker 4: Yeah. 409 00:23:01,640 --> 00:23:04,400 Speaker 2: So, I'll see other descriptions that are important here. There's 410 00:23:04,440 --> 00:23:08,320 Speaker 2: stocky lizards with broad heads and short fat tails, where 411 00:23:08,320 --> 00:23:11,200 Speaker 2: they indeed use these tails for fat storage. 412 00:23:11,480 --> 00:23:11,680 Speaker 4: Yeah. 413 00:23:11,760 --> 00:23:13,919 Speaker 3: So they often get a bunch of their meals in 414 00:23:14,000 --> 00:23:16,399 Speaker 3: one part of the year and then store up that 415 00:23:17,520 --> 00:23:20,000 Speaker 3: energy as fat reserves in the tail, which they can 416 00:23:20,000 --> 00:23:22,920 Speaker 3: then live off of for the leaner parts of the year. 417 00:23:23,280 --> 00:23:25,840 Speaker 2: That's right, I've read that. Yeah, their meals are few 418 00:23:25,840 --> 00:23:29,480 Speaker 2: and far between, somewhere between five and ten meals per 419 00:23:29,560 --> 00:23:32,840 Speaker 2: year for a helo monster. So. Beaded lizards in general 420 00:23:32,960 --> 00:23:35,480 Speaker 2: spend most of their time in burrows and they avoid 421 00:23:35,520 --> 00:23:38,919 Speaker 2: extreme temperatures, so only during cooler spring months are they 422 00:23:38,960 --> 00:23:41,440 Speaker 2: going to come out during the day at all. They 423 00:23:41,480 --> 00:23:44,960 Speaker 2: forage on the ground, but can also climb trees as well. 424 00:23:45,080 --> 00:23:48,040 Speaker 2: Even the helo monster who if you again, if you certainly, 425 00:23:48,080 --> 00:23:50,680 Speaker 2: if you've seen them at the zoo or in some 426 00:23:50,720 --> 00:23:54,320 Speaker 2: sort of you know, enclosed environment like that, they don't 427 00:23:54,320 --> 00:23:56,120 Speaker 2: really look like they're going to be scaling a lot 428 00:23:56,119 --> 00:23:58,680 Speaker 2: of trees. They look like they are very ground based 429 00:23:59,040 --> 00:24:03,400 Speaker 2: and certainly under round based. But you have to consider 430 00:24:03,480 --> 00:24:07,600 Speaker 2: what their favorite meals are, and so they're they're foraging, 431 00:24:07,640 --> 00:24:10,240 Speaker 2: but what are they foraging for. They're generally looking for 432 00:24:11,040 --> 00:24:14,960 Speaker 2: eggs and young prey, so young mammalian prey generally like 433 00:24:15,119 --> 00:24:18,719 Speaker 2: rodents or I believe baby rabbits also come up as 434 00:24:18,760 --> 00:24:19,320 Speaker 2: a favorite. 435 00:24:19,440 --> 00:24:23,640 Speaker 3: They love little cottontails, baby birds, eggs. They're nest raiders, 436 00:24:23,720 --> 00:24:25,760 Speaker 3: nest rating specialists, and so. 437 00:24:25,720 --> 00:24:27,800 Speaker 2: You got to go where the nests are, and certainly 438 00:24:27,840 --> 00:24:29,840 Speaker 2: with a lot of bird species, they may be up 439 00:24:29,880 --> 00:24:31,640 Speaker 2: in the in the trees, and so that is where 440 00:24:31,680 --> 00:24:34,679 Speaker 2: the HeLa monster will go. If you look around and on, 441 00:24:34,760 --> 00:24:39,600 Speaker 2: you can find some images of HeLa monsters possibly in 442 00:24:39,640 --> 00:24:42,000 Speaker 2: the act of climbing, or at least they're halfway up 443 00:24:42,000 --> 00:24:45,280 Speaker 2: a tree or small tree. Anyway, again, you have to 444 00:24:45,320 --> 00:24:49,040 Speaker 2: consider their environments and what constitutes a tree and helo 445 00:24:49,119 --> 00:24:49,800 Speaker 2: monster land. 446 00:24:50,560 --> 00:24:54,400 Speaker 3: Yeah, they're not going to be a lot of sorry, 447 00:24:54,440 --> 00:24:56,119 Speaker 3: is it going to be a lot of desert stuff 448 00:24:56,200 --> 00:24:58,080 Speaker 3: like maybe mesquite or pelleverity? 449 00:24:58,480 --> 00:25:00,400 Speaker 2: Yeah, I think so. Yeah, not going to be yeah, 450 00:25:00,440 --> 00:25:05,680 Speaker 2: redwoods or gigantic trees of that that nature. Uh, but yeah, 451 00:25:05,720 --> 00:25:09,159 Speaker 2: they so some of the nests and an opportunities to 452 00:25:09,160 --> 00:25:11,119 Speaker 2: feed are going to be up high, but a lot 453 00:25:11,160 --> 00:25:12,960 Speaker 2: of them are going to be in the ground, and 454 00:25:13,000 --> 00:25:15,840 Speaker 2: so they can use their powerful fore limbs to go 455 00:25:15,920 --> 00:25:19,280 Speaker 2: after those nests as well. Uh. And they yeah, and 456 00:25:19,640 --> 00:25:22,879 Speaker 2: according to Beck and his work, they feed almost exclusively 457 00:25:22,960 --> 00:25:25,840 Speaker 2: on vertebrate nest contents. They'll eat other things as well, 458 00:25:26,480 --> 00:25:29,320 Speaker 2: but vertebrate nest contents that's what they go for. 459 00:25:29,640 --> 00:25:30,000 Speaker 4: Okay. 460 00:25:31,080 --> 00:25:34,560 Speaker 2: Beck explains that few other lizards or snakes are really 461 00:25:34,600 --> 00:25:37,480 Speaker 2: going to share this uh, this this niche because it 462 00:25:37,560 --> 00:25:40,680 Speaker 2: is a challenging one to choose in life. We see 463 00:25:40,680 --> 00:25:44,439 Speaker 2: this with other examples of of of organisms where if 464 00:25:44,440 --> 00:25:49,040 Speaker 2: you have a very specialized diet, uh, it may bring richness, 465 00:25:49,040 --> 00:25:53,879 Speaker 2: but it also can bring you know, seasonable availability and 466 00:25:53,920 --> 00:25:57,720 Speaker 2: so forth. So so that's definitely in play here. Egg 467 00:25:57,800 --> 00:26:01,320 Speaker 2: layers and and and eating animals are going to be 468 00:26:01,520 --> 00:26:03,520 Speaker 2: you know, more active at certain times of the year 469 00:26:03,560 --> 00:26:06,280 Speaker 2: that's when they're going to produce. But also if you 470 00:26:06,400 --> 00:26:10,359 Speaker 2: are eating mostly eggs or the young, these are prize commodities, 471 00:26:10,400 --> 00:26:14,639 Speaker 2: a lot of energy goes into creating them, and then 472 00:26:15,440 --> 00:26:16,760 Speaker 2: this could and then a lot of energy is going 473 00:26:16,800 --> 00:26:20,120 Speaker 2: to go into either secreting them away or actively protecting them. 474 00:26:20,600 --> 00:26:23,680 Speaker 2: So so that is also a factor. And to even 475 00:26:23,800 --> 00:26:26,479 Speaker 2: find them, especially if they're hidden in some way, you 476 00:26:26,480 --> 00:26:29,800 Speaker 2: have to be pretty sensitive to their uh, to to 477 00:26:29,840 --> 00:26:32,800 Speaker 2: their their their their their chemical signal. You have to 478 00:26:32,840 --> 00:26:36,840 Speaker 2: have a very chemically sensitive organism and in organism that 479 00:26:36,880 --> 00:26:41,119 Speaker 2: has a pretty good memory. So so again you have 480 00:26:41,160 --> 00:26:45,800 Speaker 2: to factor that into the evolutionary direction that monitor that 481 00:26:45,840 --> 00:26:48,800 Speaker 2: these uh, these beaded lizards and specifically uh, the HeLa 482 00:26:48,880 --> 00:26:51,760 Speaker 2: monster have gone uh, so you have to have you 483 00:26:51,880 --> 00:26:55,440 Speaker 2: end up with a devoted egg eater slash baby eater, 484 00:26:56,000 --> 00:26:58,760 Speaker 2: nest rat or that has to go for long stretches 485 00:26:58,800 --> 00:27:04,000 Speaker 2: without being able to eat. And indeed we see that 486 00:27:04,080 --> 00:27:06,919 Speaker 2: with the Helo monsters diet again, eating five to ten 487 00:27:07,000 --> 00:27:09,520 Speaker 2: times a year, and those meals are not going to 488 00:27:09,560 --> 00:27:13,520 Speaker 2: be evenly spread out now they get at their Their 489 00:27:13,560 --> 00:27:17,359 Speaker 2: activity also ticks up during other key moments, of course, 490 00:27:17,440 --> 00:27:21,200 Speaker 2: during breeding season and mate selection season. This is when 491 00:27:21,240 --> 00:27:23,760 Speaker 2: the males of the Helo monsters are going to compete 492 00:27:23,800 --> 00:27:27,720 Speaker 2: through what is often described as fierce combat, though I'm 493 00:27:27,720 --> 00:27:31,919 Speaker 2: to understand it's mostly intense wrestling with some nibs. So 494 00:27:32,359 --> 00:27:34,000 Speaker 2: they're going to bite each other, but they're not going 495 00:27:34,080 --> 00:27:37,600 Speaker 2: to go full on venom inducing bites. These are going 496 00:27:37,640 --> 00:27:40,960 Speaker 2: to be I'm not going to say loving bites. They're 497 00:27:41,000 --> 00:27:47,960 Speaker 2: still done in an offensive way. They're still competing, but yeah, 498 00:27:48,080 --> 00:27:49,920 Speaker 2: not going to be full on bites. The mating takes 499 00:27:50,000 --> 00:27:53,280 Speaker 2: place in late spring, resulting in up to a dozen eggs, 500 00:27:53,280 --> 00:27:55,159 Speaker 2: which require ten months before hatching. 501 00:27:55,680 --> 00:27:57,480 Speaker 3: So like in a lot of other species, you're going 502 00:27:57,560 --> 00:28:00,520 Speaker 3: to have, especially males, competing with each each other for 503 00:28:00,640 --> 00:28:02,080 Speaker 3: opportunities to mate. 504 00:28:02,600 --> 00:28:06,159 Speaker 2: Yes, absolutely, Yeah, they're going to wrestle around, they're going 505 00:28:06,200 --> 00:28:09,480 Speaker 2: to nib each other, and then it's going to you know, 506 00:28:09,880 --> 00:28:12,800 Speaker 2: lead to mate selection and the production of these eggs. 507 00:28:12,960 --> 00:28:13,840 Speaker 3: Yeah. 508 00:28:14,080 --> 00:28:15,480 Speaker 2: Now, this is where we're going to come back to 509 00:28:15,480 --> 00:28:18,720 Speaker 2: that study we referenced already from Shuitt. This is a 510 00:28:18,760 --> 00:28:22,879 Speaker 2: twenty twenty three study from cal poly Pomona and it 511 00:28:23,080 --> 00:28:26,480 Speaker 2: concerns female female aggression in the HeLa monster and they 512 00:28:26,520 --> 00:28:29,080 Speaker 2: found that, Okay, this is you know, definitely the case 513 00:28:29,119 --> 00:28:32,760 Speaker 2: when males fight each other intense wrestling but mostly just 514 00:28:32,960 --> 00:28:35,960 Speaker 2: nibbing at each other with their mouths. But when females 515 00:28:36,000 --> 00:28:38,840 Speaker 2: fight each other, and they may fight each other for 516 00:28:38,840 --> 00:28:43,000 Speaker 2: a few different reasons, you know, territorial defense, an acquisition, 517 00:28:43,160 --> 00:28:49,000 Speaker 2: mate defense, parental care slash cannibalism prevention. When the females fight, 518 00:28:49,160 --> 00:28:53,400 Speaker 2: they really don't hold anything bite. They're full on bites here, 519 00:28:54,320 --> 00:28:57,600 Speaker 2: which is which is interesting, Like they're not going it's 520 00:28:57,600 --> 00:29:00,600 Speaker 2: like they're not competing for mating here. They are just 521 00:29:01,200 --> 00:29:05,840 Speaker 2: all out like for instance, defending their young and or 522 00:29:05,880 --> 00:29:10,880 Speaker 2: preventing cannibalism from occurring. Because again, helo monsters are nest raiders, 523 00:29:10,920 --> 00:29:14,080 Speaker 2: they are not above rating other heelo monster nests. 524 00:29:14,400 --> 00:29:17,600 Speaker 3: The authors of the study talk about reasons why the 525 00:29:18,720 --> 00:29:21,680 Speaker 3: intensity and the violence of the fighting between the females 526 00:29:21,760 --> 00:29:26,240 Speaker 3: might be greater than that of the competition between males, 527 00:29:26,760 --> 00:29:29,080 Speaker 3: and one idea they talk about that I thought was 528 00:29:29,120 --> 00:29:33,240 Speaker 3: interesting is that it could be because the males have 529 00:29:33,440 --> 00:29:40,200 Speaker 3: a ritualized system for handling intersex conflict. So because they 530 00:29:40,280 --> 00:29:43,720 Speaker 3: have this system of competing with one another for mates, 531 00:29:43,800 --> 00:29:47,800 Speaker 3: they have this ritualized wrestling type of thing where they 532 00:29:47,960 --> 00:29:51,280 Speaker 3: can sort of have a proxy for all out fighting 533 00:29:51,320 --> 00:29:55,719 Speaker 3: by competing to show endurance in wrestling or these displays, 534 00:29:56,280 --> 00:29:59,200 Speaker 3: which is another interesting example of something we've talked about 535 00:29:59,280 --> 00:30:02,320 Speaker 3: on the show before of like a lot of the 536 00:30:02,400 --> 00:30:05,320 Speaker 3: things we see in nature that we think of as 537 00:30:05,600 --> 00:30:11,640 Speaker 3: fighting or aggression are actually ways of avoiding fighting or aggression. 538 00:30:11,760 --> 00:30:12,160 Speaker 2: M hmm. 539 00:30:12,960 --> 00:30:15,680 Speaker 3: It's kind of a kind of an interesting paradox there, 540 00:30:15,720 --> 00:30:18,560 Speaker 3: Like some of the most aggressive stuff you might see 541 00:30:18,600 --> 00:30:22,360 Speaker 3: animals doing is actually behaviors they have evolved in order 542 00:30:22,400 --> 00:30:24,280 Speaker 3: to avoid all out violence. 543 00:30:25,040 --> 00:30:28,400 Speaker 2: Yeah, yeah, this is This is always fascinating anytime it 544 00:30:28,440 --> 00:30:30,680 Speaker 2: comes up. You know that we have we certainly have 545 00:30:30,760 --> 00:30:34,240 Speaker 2: more extreme cases where essentially, like two males can just 546 00:30:34,280 --> 00:30:36,960 Speaker 2: stare each other down. One has a clear size advantage 547 00:30:37,040 --> 00:30:39,479 Speaker 2: or some other clear advantage. The other one's just going 548 00:30:39,520 --> 00:30:41,160 Speaker 2: to back down. It's like, okay, we don't even have 549 00:30:41,240 --> 00:30:43,520 Speaker 2: to fight. We can see how this would play out. 550 00:30:44,000 --> 00:30:45,680 Speaker 2: And this is kind of more like sort of a 551 00:30:45,720 --> 00:30:49,280 Speaker 2: downstream version of a similar scenario. It's like like, okay, 552 00:30:49,280 --> 00:30:51,920 Speaker 2: we can sort of go fifty percent in this battle, 553 00:30:52,240 --> 00:30:54,880 Speaker 2: and then we know how a full one hundred percent 554 00:30:54,920 --> 00:30:56,520 Speaker 2: battle between the two of us would go. But we 555 00:30:56,560 --> 00:30:59,840 Speaker 2: don't need to go there. You know, the winner wants 556 00:30:59,880 --> 00:31:02,239 Speaker 2: to go on in mate, the loser would like to 557 00:31:02,240 --> 00:31:05,480 Speaker 2: go on and successfully mate and or win other competitions. 558 00:31:05,800 --> 00:31:07,920 Speaker 2: It serves everyone's best interest if this is how it 559 00:31:07,960 --> 00:31:08,440 Speaker 2: plays out. 560 00:31:08,640 --> 00:31:11,680 Speaker 3: I guess it usually only works out for like a 561 00:31:12,280 --> 00:31:16,840 Speaker 3: maybe a younger individual that doesn't look as strong but 562 00:31:16,960 --> 00:31:20,200 Speaker 3: could actually win in a fight, like would not win 563 00:31:20,280 --> 00:31:22,600 Speaker 3: the bluff, but would win the fight. But that you know, 564 00:31:22,640 --> 00:31:25,120 Speaker 3: that's not going to happen all that often, right, Right, 565 00:31:26,240 --> 00:31:27,840 Speaker 3: One more thing I did want to mention from this 566 00:31:27,880 --> 00:31:31,040 Speaker 3: Schwitt study, So it talks about another thing that was 567 00:31:31,200 --> 00:31:34,800 Speaker 3: missing from the male male aggression usually but was present 568 00:31:34,880 --> 00:31:38,920 Speaker 3: in the female female aggression. Was so they will bite, 569 00:31:39,080 --> 00:31:41,800 Speaker 3: do it full on biting, and also will do this 570 00:31:41,880 --> 00:31:46,120 Speaker 3: thing they call lateral rotation. Did you get to this 571 00:31:46,240 --> 00:31:49,560 Speaker 3: part here where they're like they compared it actually to 572 00:31:49,600 --> 00:31:50,880 Speaker 3: the crocodilian death. 573 00:31:51,680 --> 00:31:52,360 Speaker 2: Yeah. 574 00:31:52,400 --> 00:31:54,800 Speaker 3: So you know, if you've seen crocodile sometimes when they 575 00:31:54,840 --> 00:31:58,760 Speaker 3: get a bite of something, either grasping part of a 576 00:31:58,800 --> 00:32:02,280 Speaker 3: prey animal that still or just getting part of a carcass, 577 00:32:02,280 --> 00:32:05,280 Speaker 3: you know, like even baby crocodilians that are trying to 578 00:32:05,440 --> 00:32:08,240 Speaker 3: tear off pieces of flesh from from an already dead 579 00:32:08,280 --> 00:32:11,160 Speaker 3: carcass or something. You know, they'll get a bite of 580 00:32:11,200 --> 00:32:14,760 Speaker 3: something in their mouth and instinctually just start spinning about 581 00:32:14,800 --> 00:32:17,800 Speaker 3: wildly in the water. And so in the study, I 582 00:32:17,800 --> 00:32:20,640 Speaker 3: thought it's interesting that even though these lizards are not 583 00:32:20,760 --> 00:32:24,120 Speaker 3: super closely related to crocodilians, they have a similar impulse. 584 00:32:24,200 --> 00:32:27,840 Speaker 3: I guess maybe you know, they are these elongated reptiles, 585 00:32:27,880 --> 00:32:31,440 Speaker 3: so they grab hold and then they just start spinning around. 586 00:32:31,800 --> 00:32:36,040 Speaker 2: If you like. Like I have watched any number of 587 00:32:36,320 --> 00:32:39,120 Speaker 2: like b movies from the fifties and sixties that feature 588 00:32:39,240 --> 00:32:44,440 Speaker 2: dinosaurs which are actually elongated lizards, some monitors, you know, 589 00:32:44,480 --> 00:32:48,520 Speaker 2: some beaded lizards for example, engaging in combat with each 590 00:32:48,520 --> 00:32:51,880 Speaker 2: other that they're generally you're going to see this sort 591 00:32:51,920 --> 00:32:55,920 Speaker 2: of wrestling going on. Yeah, bite and then roll, Yeah, 592 00:32:55,920 --> 00:32:57,120 Speaker 2: a lot of rolling around. 593 00:32:58,280 --> 00:33:00,800 Speaker 3: Oh. But another thing they mentioned in this paper is 594 00:33:01,000 --> 00:33:05,640 Speaker 3: the role of armored protection in these fights. Like the 595 00:33:05,680 --> 00:33:08,880 Speaker 3: osteoderms themselves the little bony warts under the skin. 596 00:33:09,480 --> 00:33:11,840 Speaker 2: Yeah, yeah, this does seem to aid them in these 597 00:33:12,160 --> 00:33:16,120 Speaker 2: contests between males. Also protects them against would be predators, 598 00:33:16,600 --> 00:33:20,000 Speaker 2: as does their venomous bite. More on this in a second. 599 00:33:20,920 --> 00:33:23,600 Speaker 2: And also that colorization, as we mentioned, it serves as 600 00:33:23,640 --> 00:33:26,760 Speaker 2: both warning and camouflage. So Beck points out that the 601 00:33:26,800 --> 00:33:29,400 Speaker 2: color patterns seem to serve as camo at a distance, 602 00:33:29,680 --> 00:33:32,840 Speaker 2: but a warning close up. A warning, of course, of 603 00:33:32,880 --> 00:33:37,400 Speaker 2: their venom, which, at least in their current form, contrary 604 00:33:37,440 --> 00:33:42,760 Speaker 2: to every reptile outside of the heloderm lizards, has no 605 00:33:42,840 --> 00:33:48,480 Speaker 2: offensive or predatory purpose. It's purely defensive. You know. You 606 00:33:48,520 --> 00:33:51,040 Speaker 2: can contrast this again with the komodo dragons, who you know, 607 00:33:51,040 --> 00:33:53,440 Speaker 2: they have venom, but it aids to some degree in 608 00:33:53,480 --> 00:33:58,240 Speaker 2: bringing down their prey helo monsters. And there can they 609 00:33:58,320 --> 00:34:02,680 Speaker 2: just have this really powerful, full chemical weapon on hand 610 00:34:02,760 --> 00:34:06,440 Speaker 2: as a defense. And it's kind of puzzling, right. It's 611 00:34:06,480 --> 00:34:09,000 Speaker 2: like if you showed up at someone's house and the 612 00:34:09,160 --> 00:34:11,239 Speaker 2: house and you're like, hey, what's that over there, it's like, oh, yeah, 613 00:34:11,280 --> 00:34:14,160 Speaker 2: that's my self defense system. It's saren gas. I just 614 00:34:14,239 --> 00:34:17,239 Speaker 2: keep it on hand. It would raise questions like why 615 00:34:17,239 --> 00:34:20,120 Speaker 2: do you have sarin gas as a like a home 616 00:34:20,160 --> 00:34:22,520 Speaker 2: defense system? Like did you have it for some other 617 00:34:22,560 --> 00:34:25,319 Speaker 2: purpose originally and you just have kept it around for this. 618 00:34:25,800 --> 00:34:26,960 Speaker 2: It's an odd choice. 619 00:34:27,440 --> 00:34:30,680 Speaker 3: Now. One thing that's interesting is it does seem to 620 00:34:30,719 --> 00:34:33,120 Speaker 3: be the case that the venom of the heel a 621 00:34:33,160 --> 00:34:37,600 Speaker 3: monster is almost entirely or entirely for defense. But this 622 00:34:37,800 --> 00:34:40,360 Speaker 3: was not always known. For a long time, it was 623 00:34:40,400 --> 00:34:43,520 Speaker 3: a contentious issue or a source of confusion, like was 624 00:34:43,560 --> 00:34:46,920 Speaker 3: it for predation or was it for defense? It does 625 00:34:46,960 --> 00:34:49,520 Speaker 3: seem to be for defense, and we'll talk about reasons 626 00:34:49,520 --> 00:34:53,400 Speaker 3: for that later, and they're pretty interesting. But I wanted 627 00:34:53,440 --> 00:34:56,480 Speaker 3: to talk briefly about the heel a monster bite and 628 00:34:56,719 --> 00:35:00,480 Speaker 3: its venom So again, one of my main sources is 629 00:35:00,520 --> 00:35:03,400 Speaker 3: going to be that book by Daniel Beck, The Biology 630 00:35:03,400 --> 00:35:06,040 Speaker 3: of HeLa Monsters and Beaded Lizards, But I was also 631 00:35:06,040 --> 00:35:08,360 Speaker 3: reading some other sources we can talk about as we 632 00:35:08,400 --> 00:35:12,839 Speaker 3: go along. As we mentioned earlier, the Heloderma lizards are 633 00:35:12,880 --> 00:35:16,279 Speaker 3: known for being among the few, or depending on your definitions, 634 00:35:16,320 --> 00:35:19,880 Speaker 3: the only venomous lizards on Earth. But it took a 635 00:35:19,920 --> 00:35:23,319 Speaker 3: long time to get to full agreement among everybody in 636 00:35:23,640 --> 00:35:27,799 Speaker 3: the specialist sort of herpetology community that these lizards were 637 00:35:27,960 --> 00:35:31,879 Speaker 3: actually venomous. Beca gives this kind of chronicle of the 638 00:35:31,920 --> 00:35:35,800 Speaker 3: history of this controversy, talking about how in the later 639 00:35:35,840 --> 00:35:39,680 Speaker 3: half of the nineteenth century you did have inklings of venomousness, 640 00:35:39,680 --> 00:35:42,600 Speaker 3: some people had made reports of this kind. He says 641 00:35:42,640 --> 00:35:45,840 Speaker 3: that some of the sources at this time comment on 642 00:35:45,880 --> 00:35:49,440 Speaker 3: the quote vile nature of Heloderma. I love these, you know, 643 00:35:49,480 --> 00:35:54,279 Speaker 3: in the older sources they're not as clinical and they're 644 00:35:54,280 --> 00:35:57,360 Speaker 3: not as clinical and reserved as modern sources are, and 645 00:35:57,400 --> 00:35:59,880 Speaker 3: talking about these reptiles, they make kind of moral judgment 646 00:36:00,080 --> 00:36:04,680 Speaker 3: from the animals they talk about, but also that you know, 647 00:36:04,719 --> 00:36:08,920 Speaker 3: some authors in the late later nineteenth century looked at 648 00:36:08,960 --> 00:36:12,000 Speaker 3: things like, well, it's teeth have these grooves in them, 649 00:36:12,040 --> 00:36:15,040 Speaker 3: what are those grooves for? That could be for delivering 650 00:36:15,120 --> 00:36:18,880 Speaker 3: venom of some sort. And then in the eighteen eighties 651 00:36:18,960 --> 00:36:22,040 Speaker 3: there were some dissections of Hiloderma looking at their venom 652 00:36:22,120 --> 00:36:26,600 Speaker 3: glands and experiments which showed that Heloderma saliva was toxic 653 00:36:26,680 --> 00:36:30,440 Speaker 3: to other animals. But this did not settle the matter, 654 00:36:30,480 --> 00:36:33,120 Speaker 3: because then more research was published later in the same 655 00:36:33,160 --> 00:36:37,960 Speaker 3: decade showing that Heloderma saliva had no toxic effects. Beck 656 00:36:38,040 --> 00:36:41,160 Speaker 3: thinks that this false negative about the toxicity of the 657 00:36:41,200 --> 00:36:45,360 Speaker 3: saliva was probably a result of samples being collected wrong. 658 00:36:45,480 --> 00:36:48,760 Speaker 3: He doesn't elaborate, but I wonder if this means somehow 659 00:36:49,880 --> 00:36:53,160 Speaker 3: that the researchers were collecting saliva that did not have 660 00:36:53,239 --> 00:36:56,319 Speaker 3: venom in it, because as we'll mention, it's you know, 661 00:36:56,400 --> 00:37:00,560 Speaker 3: the venom is sort of is injected from glands into mouth. 662 00:37:01,960 --> 00:37:06,879 Speaker 3: In the eighteen nineties, researchers extracted venom directly from heloderma 663 00:37:07,040 --> 00:37:11,240 Speaker 3: venom glands and injected it into small vertebrates, which resulted 664 00:37:11,280 --> 00:37:16,200 Speaker 3: in death. But then others remained skeptical. Here's the thing 665 00:37:16,239 --> 00:37:19,280 Speaker 3: I alluded to earlier. There was this one researcher named Snow, 666 00:37:19,520 --> 00:37:22,480 Speaker 3: last named Snow who got a helo monster bite, and 667 00:37:22,520 --> 00:37:24,640 Speaker 3: he was like, Eh, no big deal. I don't think 668 00:37:24,680 --> 00:37:27,880 Speaker 3: they're venomous. So maybe he just got a dry bite 669 00:37:27,880 --> 00:37:31,680 Speaker 3: with little or no venom delivered unclear, But Beck also 670 00:37:31,840 --> 00:37:34,840 Speaker 3: quotes an author named Goodfellow, writing in the year nineteen 671 00:37:34,840 --> 00:37:37,319 Speaker 3: oh seven, who says, you know, at this point the 672 00:37:37,320 --> 00:37:40,000 Speaker 3: case is closed. It is not venomous. It can be 673 00:37:40,120 --> 00:37:44,680 Speaker 3: conclusively demonstrated. Quote that the bite of the monster is innocuous. 674 00:37:44,800 --> 00:37:49,399 Speaker 3: Per se as we know this was completely wrong, And 675 00:37:49,520 --> 00:37:52,640 Speaker 3: in nineteen thirteen a book was published by the Carnegie 676 00:37:52,719 --> 00:37:57,279 Speaker 3: Institute of Washington that had details on extensive experiments by 677 00:37:57,280 --> 00:38:01,080 Speaker 3: eleven different contributors on the venom of Hiloderma, and this 678 00:38:01,200 --> 00:38:04,920 Speaker 3: book and then subsequent papers in the following decade finally 679 00:38:05,000 --> 00:38:07,920 Speaker 3: had everybody convinced that the lizards were venomous. So it 680 00:38:07,920 --> 00:38:11,040 Speaker 3: seems like by the nineteen twenties. Everybody's on the same page. Okay, 681 00:38:11,120 --> 00:38:15,840 Speaker 3: yes they are venomous. So to picture how Heloderma in 682 00:38:15,960 --> 00:38:20,680 Speaker 3: venomation works, it helps to contrast it with the other 683 00:38:20,800 --> 00:38:24,440 Speaker 3: venomous reptile you're probably thinking of, which is venomous snakes. 684 00:38:25,120 --> 00:38:28,240 Speaker 3: In a venomous snake, the venom glands and the venom 685 00:38:28,280 --> 00:38:32,960 Speaker 3: conducting teeth the fangs are in the upper jaw. In 686 00:38:33,040 --> 00:38:37,880 Speaker 3: most venomous snakes, the fangs will produce deep puncture wounds 687 00:38:37,880 --> 00:38:41,320 Speaker 3: with a bite, and then the snake's venom glands, often 688 00:38:41,480 --> 00:38:45,200 Speaker 3: located sort of behind or under the eyes, inject venom 689 00:38:45,280 --> 00:38:49,280 Speaker 3: through ducts into the wound through holes in the hollow fangs. 690 00:38:49,960 --> 00:38:53,720 Speaker 3: On the other hand, in Heloderma suspectum, the helo monster, 691 00:38:54,000 --> 00:38:57,480 Speaker 3: the venom glands are in the lower jaw, and the 692 00:38:57,600 --> 00:39:02,200 Speaker 3: venom conducting teeth are mostly the lower teeth, So the 693 00:39:02,280 --> 00:39:06,080 Speaker 3: venom conducting teeth here are not going to be injecting 694 00:39:06,239 --> 00:39:09,600 Speaker 3: venom like the fangs of a cobra. If you see 695 00:39:09,640 --> 00:39:12,719 Speaker 3: the venom glands of Heloderma illustrated, they sort of make 696 00:39:12,760 --> 00:39:15,799 Speaker 3: the lizard look a bit jowy. There's a Don Corleone 697 00:39:15,840 --> 00:39:19,040 Speaker 3: thing going on and the venom glands. So there are 698 00:39:19,080 --> 00:39:23,319 Speaker 3: these multi lobed little protuberances on the lower jaw. They 699 00:39:23,320 --> 00:39:25,040 Speaker 3: line the lower jaw and you can see them in 700 00:39:25,080 --> 00:39:28,640 Speaker 3: like three or four lobes down there, and each little 701 00:39:28,680 --> 00:39:31,720 Speaker 3: plump lobe is connected to the gums via a duct. 702 00:39:31,880 --> 00:39:35,880 Speaker 3: So the HeLa monster has very sharp, long teeth with 703 00:39:36,160 --> 00:39:40,160 Speaker 3: grooves running up the teeth from the base, and when 704 00:39:40,200 --> 00:39:44,200 Speaker 3: the lizard bites, venom is expressed from the glands out 705 00:39:44,200 --> 00:39:47,440 Speaker 3: through the ducts, flooding around the base of the teeth, 706 00:39:47,880 --> 00:39:51,200 Speaker 3: and then it is conducted up the teeth and into 707 00:39:51,320 --> 00:39:55,200 Speaker 3: the wounds of the bite victim via capillary action. So 708 00:39:55,520 --> 00:39:58,280 Speaker 3: the same way that if you have a very thin straw, 709 00:39:58,480 --> 00:40:01,560 Speaker 3: you can see liquid just natured truly climb up the straw, 710 00:40:01,640 --> 00:40:05,160 Speaker 3: even without any suction being applied. It's just the capillary 711 00:40:05,239 --> 00:40:07,640 Speaker 3: action caused by the surface tension of the liquid it 712 00:40:07,680 --> 00:40:10,200 Speaker 3: wants to climb up through the very narrow channel. Same 713 00:40:10,239 --> 00:40:12,400 Speaker 3: thing happens. It climbs up through the teeth and is 714 00:40:12,440 --> 00:40:16,800 Speaker 3: conducted into the wound. But there's also just getting venom 715 00:40:16,880 --> 00:40:20,120 Speaker 3: into the wound through good old fashioned mashing and grinding. 716 00:40:21,200 --> 00:40:23,360 Speaker 2: Yeah, that's that's I think one of the really telling 717 00:40:23,360 --> 00:40:25,480 Speaker 2: things about the HeLa monster is that it has to 718 00:40:25,600 --> 00:40:28,880 Speaker 2: chew the venom into the target, which certainly feels like 719 00:40:28,920 --> 00:40:34,640 Speaker 2: a less sort of biotechnolog technologically advanced delivery system compared 720 00:40:34,680 --> 00:40:37,280 Speaker 2: to like a you know, a cobra or a viper 721 00:40:37,320 --> 00:40:39,839 Speaker 2: that you could almost think of their fangs as being 722 00:40:39,880 --> 00:40:41,400 Speaker 2: like little hypodermic needles. 723 00:40:41,760 --> 00:40:44,120 Speaker 3: Yes, I mean, as we know, there is no up 724 00:40:44,239 --> 00:40:47,840 Speaker 3: or down in evolution, so there's no actual like you know, 725 00:40:48,360 --> 00:40:51,560 Speaker 3: more or less sophisticated in a way. That's that's just 726 00:40:51,719 --> 00:40:54,600 Speaker 3: sort of an interpretive overlay that we put on things 727 00:40:55,120 --> 00:40:57,759 Speaker 3: that doesn't really connect anything real in nature. But it 728 00:40:57,760 --> 00:41:00,680 Speaker 3: does feel that way. It feels like a less specialize, 729 00:41:00,760 --> 00:41:04,440 Speaker 3: less sophisticated method of delivery for venom than something like 730 00:41:04,520 --> 00:41:05,760 Speaker 3: cobra fangs. 731 00:41:05,640 --> 00:41:08,319 Speaker 2: Right, And we can certainly understand this a lot more 732 00:41:08,400 --> 00:41:11,680 Speaker 2: by just thinking and continue to discuss how a helo 733 00:41:11,760 --> 00:41:17,000 Speaker 2: monster uses its venom, like what role it has in 734 00:41:17,320 --> 00:41:21,680 Speaker 2: its life as opposed to venomous snakes. But the way 735 00:41:21,680 --> 00:41:23,680 Speaker 2: the Helo monster is going about it, it seems to 736 00:41:23,719 --> 00:41:25,840 Speaker 2: work well for the Helo monster. 737 00:41:36,239 --> 00:41:40,120 Speaker 3: In this book, chapter Beck explains one interesting idea related 738 00:41:40,160 --> 00:41:44,440 Speaker 3: to how the helodermal lizards prepare to deliver their venom. 739 00:41:45,000 --> 00:41:47,439 Speaker 3: So if you approach one of these things, and again 740 00:41:47,640 --> 00:41:49,879 Speaker 3: I recommend if you're out in nature, don't mess with them, 741 00:41:50,400 --> 00:41:54,680 Speaker 3: keep your distance. But if something approaches, a threatened or 742 00:41:54,760 --> 00:41:59,840 Speaker 3: agitated helodermal lizard will often open and close its jaws 743 00:42:00,040 --> 00:42:04,279 Speaker 3: repeatedly at whatever is bothering it, exposing, for one thing, 744 00:42:04,719 --> 00:42:07,440 Speaker 3: sort of showing off the inside of the mouth, exposing 745 00:42:07,480 --> 00:42:10,160 Speaker 3: this pink, purple white inside of the mouth is very 746 00:42:10,160 --> 00:42:13,040 Speaker 3: different color is usually than the outside of the animal, 747 00:42:13,120 --> 00:42:15,879 Speaker 3: so that can be kind of visually shocking to see 748 00:42:15,960 --> 00:42:19,480 Speaker 3: when it spreads its jaws wide, and this is often 749 00:42:19,480 --> 00:42:22,640 Speaker 3: interpreted as a threat display, but Beck mentions that it 750 00:42:23,120 --> 00:42:26,680 Speaker 3: might have another function, which is that the opening and 751 00:42:26,760 --> 00:42:30,319 Speaker 3: closing of the jaws could serve to express venom from 752 00:42:30,320 --> 00:42:33,320 Speaker 3: the glands into the mouth and then to better coat 753 00:42:33,640 --> 00:42:37,240 Speaker 3: all the teeth with venom rather than only the pairs 754 00:42:37,239 --> 00:42:39,600 Speaker 3: of teeth in the middle lower jaw that have the 755 00:42:39,680 --> 00:42:41,279 Speaker 3: venom ducts right beneath them. 756 00:42:41,640 --> 00:42:43,400 Speaker 2: Oh wow, it's kind of like one of those fighting 757 00:42:43,440 --> 00:42:46,400 Speaker 2: games where you charge up an attack, you know, yeah, yeah, 758 00:42:46,640 --> 00:42:49,440 Speaker 2: either rapidly pushing that button or like holding back or 759 00:42:49,480 --> 00:42:50,759 Speaker 2: holding down a button. 760 00:42:50,680 --> 00:42:52,840 Speaker 3: I was thinking of in D and D, like applying 761 00:42:52,920 --> 00:42:55,720 Speaker 3: poison to all of your arrows before the light starts. 762 00:42:55,880 --> 00:42:57,120 Speaker 2: Yes, that's a good one too. 763 00:42:57,760 --> 00:43:01,480 Speaker 3: However, one thing you can say about Helo monster in 764 00:43:01,640 --> 00:43:06,680 Speaker 3: venomation is if the delivery system feels unsophisticated, the chewing 765 00:43:06,800 --> 00:43:10,040 Speaker 3: venom into the wound feels a little crude, the venom 766 00:43:10,280 --> 00:43:17,120 Speaker 3: itself is highly sophisticated. It is this fascinating, diverse, complex 767 00:43:17,239 --> 00:43:23,759 Speaker 3: cocktail of dozens of different bioactive agents, compounds, proteins, peptides, 768 00:43:23,800 --> 00:43:27,560 Speaker 3: all hormones, all different kinds of things, producing a wide 769 00:43:27,840 --> 00:43:31,640 Speaker 3: range of toxic effects. And there are some sources that 770 00:43:31,719 --> 00:43:35,000 Speaker 3: indicate it might be a more than the some of 771 00:43:35,040 --> 00:43:39,520 Speaker 3: its parts kind of situation where scientists have done a 772 00:43:39,560 --> 00:43:44,160 Speaker 3: lot of work isolating individual toxins from the Helo Monster's 773 00:43:44,200 --> 00:43:46,640 Speaker 3: venom and trying to understand them and trying to see 774 00:43:46,640 --> 00:43:49,840 Speaker 3: what they do. Of course, this will have major implications 775 00:43:49,880 --> 00:43:53,080 Speaker 3: for pharmaceuticals that we can probably discuss in the next 776 00:43:53,080 --> 00:43:55,280 Speaker 3: part in the series or at some point in the series. 777 00:43:55,760 --> 00:44:00,360 Speaker 3: So a huge array of interesting and powerful bio active 778 00:44:00,400 --> 00:44:03,680 Speaker 3: agents throughout this venom, but in some cases it has 779 00:44:03,719 --> 00:44:07,680 Speaker 3: been found that certain toxins within the venom are more 780 00:44:07,840 --> 00:44:11,399 Speaker 3: potent within the venom at what they do than they 781 00:44:11,440 --> 00:44:14,200 Speaker 3: are when they're isolated. So again, it might be more 782 00:44:14,239 --> 00:44:17,879 Speaker 3: than the sum of its parts. And of course some 783 00:44:17,920 --> 00:44:21,040 Speaker 3: of these things found in the venom or have been 784 00:44:21,040 --> 00:44:23,879 Speaker 3: the source of revolutionary drug discoveries. Again, we'll come back 785 00:44:23,920 --> 00:44:26,520 Speaker 3: to that, but I want to talk first about just 786 00:44:26,640 --> 00:44:28,680 Speaker 3: what's it like to be bitten by a HeLa monster. 787 00:44:29,760 --> 00:44:35,440 Speaker 3: First of all, incredibly unbelievably painful. People often describe it 788 00:44:35,520 --> 00:44:39,120 Speaker 3: as like being on fire. There is a fire that 789 00:44:39,200 --> 00:44:42,680 Speaker 3: you can't put out in your flesh. Another simile that 790 00:44:42,719 --> 00:44:46,359 Speaker 3: I have seen multiple times is molten hot lava has 791 00:44:46,560 --> 00:44:51,239 Speaker 3: entered your bloodstream. It's like something is burning hot and 792 00:44:51,320 --> 00:44:54,800 Speaker 3: it is flowing inside you now. And this is because 793 00:44:54,800 --> 00:44:59,719 Speaker 3: in many cases, the excruciating pain is not only localized 794 00:44:59,760 --> 00:45:02,040 Speaker 3: at the the source of the bite. It is there, 795 00:45:02,080 --> 00:45:05,200 Speaker 3: but it also tends to radiate back toward the core 796 00:45:05,280 --> 00:45:08,160 Speaker 3: of the body. So, for example, people who are bitten 797 00:45:08,200 --> 00:45:12,600 Speaker 3: on the hand often describe a sense of extreme, unbearable 798 00:45:12,680 --> 00:45:16,400 Speaker 3: burning pain that climbs up the arm and into the shoulder, 799 00:45:16,800 --> 00:45:21,120 Speaker 3: which creates distress in itself because there's this feeling of 800 00:45:21,160 --> 00:45:22,840 Speaker 3: how far is it going to go and when is 801 00:45:22,880 --> 00:45:27,320 Speaker 3: it going to stop. People who have experienced it usually 802 00:45:27,360 --> 00:45:29,560 Speaker 3: say it is the worst pain they have ever felt. 803 00:45:30,400 --> 00:45:33,640 Speaker 3: Beyond that, there are a bunch of systemic effects that 804 00:45:33,680 --> 00:45:37,719 Speaker 3: have been documented, some frequently, some occasionally, so it's not 805 00:45:37,800 --> 00:45:41,080 Speaker 3: always exactly the same array of effects, and I can't 806 00:45:41,080 --> 00:45:46,040 Speaker 3: list every reaction ever documented, but the large list includes 807 00:45:46,760 --> 00:45:50,000 Speaker 3: reduction in blood flow through the carotid artery, which is 808 00:45:50,000 --> 00:45:51,960 Speaker 3: going to mean reduced blood flow to the head and 809 00:45:52,000 --> 00:45:56,440 Speaker 3: the brain, a drop in blood pressure. Tachycardia is a 810 00:45:56,640 --> 00:46:00,440 Speaker 3: rapid heart rate when resting, and just general cardio weirdness 811 00:46:00,480 --> 00:46:06,080 Speaker 3: messing with your heart rate and your circulation. General trouble breathing, 812 00:46:06,120 --> 00:46:09,360 Speaker 3: a lot of different kinds of strange breathing, maybe shortness 813 00:46:09,360 --> 00:46:14,440 Speaker 3: of breath or difficulty with breathing in different ways. Edema, 814 00:46:14,600 --> 00:46:17,920 Speaker 3: which is swelling caused by fluid retention in body tissues. 815 00:46:17,960 --> 00:46:19,799 Speaker 3: I think this is going to be especially around the 816 00:46:19,840 --> 00:46:23,480 Speaker 3: area of the bite. Hypothermia which is a drop in 817 00:46:23,520 --> 00:46:28,600 Speaker 3: core body temperature, nausea and vomiting and other gastrointestinal distress 818 00:46:29,040 --> 00:46:33,080 Speaker 3: and internal hemorrhage and major organs, and the lungs, eyes, 819 00:46:33,280 --> 00:46:36,440 Speaker 3: digestive tract and other organs. I've seen people who suffered 820 00:46:36,440 --> 00:46:42,080 Speaker 3: helo monster bites talking about blood in their urine, so surprisingly, 821 00:46:42,239 --> 00:46:45,520 Speaker 3: despite how alarming that list is. We mentioned this earlier, 822 00:46:45,600 --> 00:46:48,640 Speaker 3: but it's kind of hard to believe that human death 823 00:46:48,680 --> 00:46:53,080 Speaker 3: from heloderma bites is very rare. There are only a 824 00:46:53,239 --> 00:46:57,400 Speaker 3: couple of possible cases of fatal bites and humans in 825 00:46:57,440 --> 00:47:02,040 Speaker 3: the past century. One of them is in dispute. Another 826 00:47:02,080 --> 00:47:04,520 Speaker 3: one was that one that's pretty recent that we talked about, 827 00:47:04,520 --> 00:47:06,640 Speaker 3: the one in twenty twenty four, the man in Colorado 828 00:47:06,680 --> 00:47:09,600 Speaker 3: who was bitten by a pet. And in cases where 829 00:47:09,600 --> 00:47:13,200 Speaker 3: death occurs, it seems usually to result from disturbances to breathing. 830 00:47:14,120 --> 00:47:18,319 Speaker 2: Yeah, I've read that in general, not referring to any 831 00:47:18,320 --> 00:47:22,480 Speaker 2: specific case here, but I've read that in general the 832 00:47:22,520 --> 00:47:25,560 Speaker 2: effects of a helo monster bite can be considerably worsened 833 00:47:26,040 --> 00:47:29,399 Speaker 2: if alcohol is in the human's bloodstream. And I think 834 00:47:29,440 --> 00:47:31,120 Speaker 2: this may be applies more to some of the more 835 00:47:31,239 --> 00:47:34,840 Speaker 2: historic alleged accounts, where we can sort of imagine a 836 00:47:34,880 --> 00:47:38,680 Speaker 2: cowboy scenario right where cowboys bitten by the HeLa monster. 837 00:47:38,920 --> 00:47:40,239 Speaker 2: What are you going to do? Well, we got to 838 00:47:40,239 --> 00:47:43,239 Speaker 2: get out the old medical kit, which is mostly a 839 00:47:43,280 --> 00:47:47,760 Speaker 2: bottle of whiskey. Have some whiskey for that helo monster bite. 840 00:47:47,800 --> 00:47:49,520 Speaker 2: It's just going to accelerate the venom. 841 00:47:50,200 --> 00:47:52,080 Speaker 3: I can imagine it the other way too, like the 842 00:47:52,120 --> 00:47:54,800 Speaker 3: cowboy's been getting into the whisky, which is what causes 843 00:47:54,800 --> 00:47:56,959 Speaker 3: the cowboy to start messing with the heli mons. 844 00:47:57,080 --> 00:48:02,520 Speaker 2: Yeah exactly, because again, most of the examples that have 845 00:48:02,560 --> 00:48:05,239 Speaker 2: been recorded where someone gets bitten by helo monsters becaus 846 00:48:05,239 --> 00:48:07,600 Speaker 2: a person was actively handling a helo monster. 847 00:48:07,840 --> 00:48:12,279 Speaker 3: Yeah. So Beck mentions differing effects of the venom on 848 00:48:12,400 --> 00:48:15,280 Speaker 3: other animals. What I was just talking about was mainly 849 00:48:16,040 --> 00:48:18,800 Speaker 3: what's been documented in humans, but there have been studies 850 00:48:18,840 --> 00:48:23,200 Speaker 3: on what happens in dogs and cats and mice. Apparently, 851 00:48:23,320 --> 00:48:26,680 Speaker 3: doses that are below the lethal dose in rodents like 852 00:48:26,760 --> 00:48:31,880 Speaker 3: mice and rats tend to cause protruding eyes and periorbital bleeding. 853 00:48:32,360 --> 00:48:32,520 Speaker 2: Oh. 854 00:48:33,239 --> 00:48:39,480 Speaker 3: Bizarrely, research has found that invertebrates seem to be basically 855 00:48:39,520 --> 00:48:42,520 Speaker 3: immune to the effects of heloderma venom. So it's kind 856 00:48:42,520 --> 00:48:46,040 Speaker 3: of a special treat for US vertebrates. The LD fifty 857 00:48:46,160 --> 00:48:48,280 Speaker 3: to the extent that it's been studied, and then that's 858 00:48:48,320 --> 00:48:51,520 Speaker 3: the dose at which fifty percent of you know, the 859 00:48:51,560 --> 00:48:55,320 Speaker 3: studied animal like mice in a lab scenario are killed 860 00:48:55,360 --> 00:48:59,000 Speaker 3: by the venom. The ld fifty seems to vary a 861 00:48:59,040 --> 00:49:02,319 Speaker 3: lot in different studies, and this, at least in part, 862 00:49:02,400 --> 00:49:05,960 Speaker 3: seems to be because the ad mixture of venom and 863 00:49:05,960 --> 00:49:08,680 Speaker 3: saliva is not constant. But it just seems like, you know, 864 00:49:08,800 --> 00:49:12,320 Speaker 3: venom lots that are taken from these animals in nature 865 00:49:12,320 --> 00:49:14,920 Speaker 3: are just not going to be of a consistent level 866 00:49:14,960 --> 00:49:15,680 Speaker 3: of potency. 867 00:49:16,880 --> 00:49:18,200 Speaker 2: And this of course reminds us of that, you know, 868 00:49:18,400 --> 00:49:21,960 Speaker 2: those previous accounts or someone said, oh, do don't worry 869 00:49:22,000 --> 00:49:23,840 Speaker 2: about they're not venomous. I got bit by one and 870 00:49:23,880 --> 00:49:27,920 Speaker 2: it's fine. It can be a variable amount of the 871 00:49:28,000 --> 00:49:29,520 Speaker 2: venom present in the saliva. 872 00:49:30,640 --> 00:49:33,359 Speaker 3: Now, this brings us to the question of what is 873 00:49:33,440 --> 00:49:37,760 Speaker 3: the venom for Beck discusses this extensively in the book. 874 00:49:38,200 --> 00:49:41,640 Speaker 3: Apparently for many years this was a subject of confusion 875 00:49:41,680 --> 00:49:44,960 Speaker 3: about Heloderma. Is the venom system of the HeLa monster 876 00:49:45,120 --> 00:49:49,000 Speaker 3: and the beaded lizard? Is it used for predation or defense? 877 00:49:49,600 --> 00:49:53,000 Speaker 3: In relatives like the venom of snakes, venom is mainly 878 00:49:53,160 --> 00:49:56,200 Speaker 3: used for predation. It can be used for defense as well, 879 00:49:56,200 --> 00:49:59,799 Speaker 3: but it's necessary for predation because the venom is used 880 00:50:00,120 --> 00:50:05,280 Speaker 3: you subdue and either kill or immobilize, and then sometimes 881 00:50:05,280 --> 00:50:10,160 Speaker 3: to digest prey. This is important because venomous snakes often 882 00:50:10,200 --> 00:50:13,799 Speaker 3: prey on animals that are relatively large and could be 883 00:50:14,040 --> 00:50:18,239 Speaker 3: dangerous to the predator, as in, they could inflict injuries 884 00:50:18,280 --> 00:50:20,640 Speaker 3: on the snake if they were able to fight back. 885 00:50:21,160 --> 00:50:24,280 Speaker 3: So in many venomous snakes, venom tends to cause things 886 00:50:24,280 --> 00:50:28,640 Speaker 3: like low blood pressure, blood clotting, and just tissue destruction 887 00:50:28,840 --> 00:50:32,880 Speaker 3: enzymatic destruction of tissue, often the tissue lining the blood vessels. 888 00:50:33,840 --> 00:50:36,759 Speaker 3: Some venomus snakes also make use of neurotoxins that can 889 00:50:36,800 --> 00:50:40,319 Speaker 3: cause muscle paralysis, and this can first of all, it 890 00:50:40,360 --> 00:50:42,880 Speaker 3: can immobilize prey, but it can also kill prey by 891 00:50:42,960 --> 00:50:47,400 Speaker 3: halting respiration, leading to death. And Beck mentions that some 892 00:50:47,960 --> 00:50:51,960 Speaker 3: snake venom may also play a role in helping snakes 893 00:50:52,120 --> 00:50:54,799 Speaker 3: pre digest their meals, which is beautiful. 894 00:50:55,120 --> 00:50:56,839 Speaker 2: It's kind of breaking it down a little bit. 895 00:50:56,920 --> 00:51:02,040 Speaker 3: Yeah, but there is a pretty significant difference between the 896 00:51:02,239 --> 00:51:05,880 Speaker 3: kind of invenomation we see from snakes and what we 897 00:51:05,960 --> 00:51:10,680 Speaker 3: get from heloderma. So a dose of heloderma venom from 898 00:51:10,680 --> 00:51:13,920 Speaker 3: a bite. While brutally painful, it tends to be a 899 00:51:13,920 --> 00:51:17,400 Speaker 3: little more locally concentrated in its effects, has less of 900 00:51:17,400 --> 00:51:22,680 Speaker 3: a tissue destroying effect, and so Beck argues that Heloderma 901 00:51:22,800 --> 00:51:27,080 Speaker 3: venom seems less specialized for subduing prey and thus is 902 00:51:27,120 --> 00:51:31,799 Speaker 3: probably more important for defense than for predation, because, again 903 00:51:32,040 --> 00:51:34,000 Speaker 3: coming back to what we talked about earlier, looking at 904 00:51:34,000 --> 00:51:37,800 Speaker 3: their ecology, how do they survive and interact with their environment? 905 00:51:38,120 --> 00:51:42,759 Speaker 3: Heloderma lizards are nest rating specialists. They attack eggs or 906 00:51:42,800 --> 00:51:47,240 Speaker 3: the helpless young of other animals, primarily birds and small mammals. 907 00:51:47,719 --> 00:51:51,480 Speaker 3: So there are you know, just you don't need a 908 00:51:51,719 --> 00:51:55,520 Speaker 3: venom to subdue a baby cotton tail rabbit or to 909 00:51:55,560 --> 00:51:59,480 Speaker 3: subdue an egg. You know these prey are they're not 910 00:51:59,600 --> 00:52:02,759 Speaker 3: very large, they're not very dangerous, and thus there's not 911 00:52:02,880 --> 00:52:05,600 Speaker 3: a big reason to see why lizards would need venom 912 00:52:05,680 --> 00:52:07,080 Speaker 3: in order to bring them down. 913 00:52:07,440 --> 00:52:10,640 Speaker 2: Like the monster setting out, it's got like this big rifle. 914 00:52:10,680 --> 00:52:12,080 Speaker 2: It's like what are you what are you hunting there? 915 00:52:12,080 --> 00:52:14,759 Speaker 2: And he's like, uh, egg doesn't make sense. 916 00:52:14,840 --> 00:52:19,840 Speaker 3: Yeah. Also, Heloderma venom does not seem to have the 917 00:52:19,880 --> 00:52:23,160 Speaker 3: tissue destroying capacities that would indicate that it is used 918 00:52:23,160 --> 00:52:25,680 Speaker 3: to help predigest prey, like it might be in the 919 00:52:25,680 --> 00:52:29,000 Speaker 3: case of some snakes. And then Beck also talks about 920 00:52:29,080 --> 00:52:33,040 Speaker 3: how field observations don't seem to indicate that heel monsters 921 00:52:33,320 --> 00:52:38,120 Speaker 3: use their venom for predation. So he's for one thing, 922 00:52:38,280 --> 00:52:40,359 Speaker 3: you know, there's not like with a snake you would 923 00:52:40,400 --> 00:52:43,320 Speaker 3: need to bite and then wait for the venom to work. 924 00:52:43,400 --> 00:52:45,640 Speaker 3: I mean, so you might bite and then back off 925 00:52:45,680 --> 00:52:49,120 Speaker 3: and then attack or bite and then wait before trying 926 00:52:49,120 --> 00:52:53,360 Speaker 3: to swallow. But Beck talks about how you know the 927 00:52:53,360 --> 00:52:57,719 Speaker 3: heel monsters they're gonna eat baby rabbits or something, they 928 00:52:58,120 --> 00:53:00,319 Speaker 3: just go in and just swallow them. You know, there's 929 00:53:00,360 --> 00:53:04,360 Speaker 3: not like chewing, pumping, when the kind of stuff you 930 00:53:04,400 --> 00:53:07,680 Speaker 3: would see when a snake needs to envenomate a prey 931 00:53:07,719 --> 00:53:10,600 Speaker 3: animal in order to get it down. Beck does mention 932 00:53:10,719 --> 00:53:16,080 Speaker 3: that in captivity sometimes he's observed HeLa monsters chewing on 933 00:53:16,520 --> 00:53:20,960 Speaker 3: already dead mice that they're being fed, but that you know, 934 00:53:21,040 --> 00:53:23,120 Speaker 3: that might be something else that might be a captivity 935 00:53:23,239 --> 00:53:29,240 Speaker 3: induced behavior or something reflexive. But generally it just observations 936 00:53:29,320 --> 00:53:32,480 Speaker 3: don't lend themselves to thinking that it has a feeding 937 00:53:32,560 --> 00:53:36,080 Speaker 3: or predation function. He says, maybe it might have more 938 00:53:36,160 --> 00:53:40,560 Speaker 3: of a predation function for juvenile lizards, Okay, like a 939 00:53:40,600 --> 00:53:44,920 Speaker 3: much smaller HeLa monster going after say again a young rabbit. 940 00:53:45,320 --> 00:53:46,240 Speaker 2: Maybe maybe rabbit. 941 00:53:46,640 --> 00:53:50,680 Speaker 3: But it seems that it's much more effective for defense. 942 00:53:50,880 --> 00:53:54,319 Speaker 3: So the main line of defense for helodermal lizards is 943 00:53:54,360 --> 00:53:57,640 Speaker 3: going to be not venom, but hiding. They spend most 944 00:53:57,680 --> 00:54:01,000 Speaker 3: of their time hiding in shelters. Now, of course, sometimes 945 00:54:01,000 --> 00:54:03,360 Speaker 3: they have to come out of these shelters to pursue 946 00:54:03,400 --> 00:54:07,080 Speaker 3: biological objectives like looking for food or looking for mates, 947 00:54:07,120 --> 00:54:09,719 Speaker 3: so they go out a wandering and if they are 948 00:54:09,760 --> 00:54:13,680 Speaker 3: caught out in the open, most of these well, for 949 00:54:13,719 --> 00:54:16,480 Speaker 3: one thing, you can contrast it with what other species 950 00:54:16,520 --> 00:54:20,000 Speaker 3: of lizards do. Most lizards, if they're caught out in 951 00:54:20,040 --> 00:54:22,680 Speaker 3: the open, will just sprint away from the threat because 952 00:54:22,719 --> 00:54:26,520 Speaker 3: they can move pretty fast. Heloderma lizards they're not fast movers. 953 00:54:26,600 --> 00:54:31,520 Speaker 3: They are large, sluggish, relatively slow moving and yes, in fact, 954 00:54:31,560 --> 00:54:35,120 Speaker 3: there are helo monster on a treadmill tests with peak 955 00:54:35,200 --> 00:54:38,799 Speaker 3: speed clocked by Beck at one point seven kilometers per 956 00:54:38,840 --> 00:54:43,920 Speaker 3: hour wo, so not super fast movers. Instead of running, 957 00:54:44,400 --> 00:54:48,360 Speaker 3: they rely on a secondary defense, which is hiding in 958 00:54:48,440 --> 00:54:52,640 Speaker 3: plain sight, so their color patterns can help camouflage them 959 00:54:52,680 --> 00:54:56,440 Speaker 3: against the background, at least when the potential predator is 960 00:54:56,480 --> 00:55:00,160 Speaker 3: at a distance. So if a predator comes with within 961 00:55:00,440 --> 00:55:04,479 Speaker 3: the range the lizard senses them, the lizard will often 962 00:55:04,560 --> 00:55:08,320 Speaker 3: freeze and press their bodies flat to the ground. However, 963 00:55:08,440 --> 00:55:11,319 Speaker 3: if a predator already saw it and kept coming, the 964 00:55:11,360 --> 00:55:13,719 Speaker 3: lizard would not be able to get away quickly enough. 965 00:55:14,040 --> 00:55:16,759 Speaker 3: So now it makes ecological sense for them to have 966 00:55:16,880 --> 00:55:20,520 Speaker 3: a third line of defense, which is venom. So the 967 00:55:20,560 --> 00:55:25,480 Speaker 3: prescription here is bite, clamp, and hold on. Usually flood 968 00:55:25,520 --> 00:55:28,320 Speaker 3: the venom up from the glands into the ducts around 969 00:55:28,320 --> 00:55:30,600 Speaker 3: the teeth, flood the venom into the wound, and then 970 00:55:30,719 --> 00:55:35,040 Speaker 3: chew more venom into the wound for the bite victim. 971 00:55:35,200 --> 00:55:39,280 Speaker 3: This leads to the kinds of effects mentioned before, excruciating pain, 972 00:55:39,520 --> 00:55:44,200 Speaker 3: drop in blood pressure, weakness, lethargy, internal hemorrhaging. It is 973 00:55:44,320 --> 00:55:49,080 Speaker 3: not a pleasant experience. Now, Beck does note an interesting 974 00:55:49,200 --> 00:55:54,360 Speaker 3: paradox if the venom is designed to drive predators away 975 00:55:55,080 --> 00:55:59,040 Speaker 3: by making the prospect of tangling with a heloderma lizard 976 00:55:59,200 --> 00:56:04,759 Speaker 3: super unpleasan why does the lizard clamp on and continue 977 00:56:04,760 --> 00:56:08,799 Speaker 3: to risk injury? While the bite victim is fighting to 978 00:56:08,880 --> 00:56:12,879 Speaker 3: remove it seems kind of counterproductive if the lizard's goal 979 00:56:13,040 --> 00:56:18,520 Speaker 3: is to deter the predator and escape unharmed. Despite the 980 00:56:18,520 --> 00:56:24,280 Speaker 3: apparent paradox. Here Beck discusses existing recorded observations of HeLa 981 00:56:24,320 --> 00:56:28,400 Speaker 3: monsters biting both humans and dogs, and in both cases, 982 00:56:28,880 --> 00:56:33,640 Speaker 3: the bite victim does not usually react by injuring the lizard. 983 00:56:33,760 --> 00:56:36,920 Speaker 3: They will usually immediately panic and just try to get 984 00:56:36,960 --> 00:56:40,240 Speaker 3: away to get the lizard off, which the bite victim 985 00:56:40,320 --> 00:56:44,480 Speaker 3: eventually does, and in most cases this happens without the 986 00:56:44,560 --> 00:56:47,400 Speaker 3: death or serious injury. Without the death of the lizard 987 00:56:47,480 --> 00:56:51,480 Speaker 3: or serious injury, A couple of recorded cases have resulted 988 00:56:51,480 --> 00:56:55,000 Speaker 3: in lizard deaths, so apparently the biting and clamping is 989 00:56:55,160 --> 00:56:58,840 Speaker 3: in the field not one hundred percent safe for the lizard, 990 00:56:59,239 --> 00:57:02,960 Speaker 3: but it does. The lizard usually does get away alive, 991 00:57:03,560 --> 00:57:05,960 Speaker 3: and I think one way of interpreting this is that 992 00:57:06,040 --> 00:57:09,399 Speaker 3: there is just sort of a calculus a trade off 993 00:57:09,520 --> 00:57:13,480 Speaker 3: that the lizard's biology is making here. So if the 994 00:57:13,520 --> 00:57:17,640 Speaker 3: lizard can hang on longer and can chew more venom 995 00:57:17,720 --> 00:57:20,760 Speaker 3: into the wound, you are more likely to produce an 996 00:57:20,840 --> 00:57:26,280 Speaker 3: intense and overwhelming reaction in the bitten predatory animal, which 997 00:57:26,400 --> 00:57:30,680 Speaker 3: I think thereafter reduces the effect that the animal comes 998 00:57:30,720 --> 00:57:33,400 Speaker 3: back and still tries to kill or eat the lizard 999 00:57:33,480 --> 00:57:38,360 Speaker 3: a second time. So, even though there is risk to 1000 00:57:38,560 --> 00:57:41,800 Speaker 3: the lizard from clamping on and continuing it to attack, 1001 00:57:42,360 --> 00:57:47,200 Speaker 3: it doesn't have a fast, efficient venom delivery system like 1002 00:57:47,280 --> 00:57:49,760 Speaker 3: the you know, the fangs of a viper or like 1003 00:57:49,800 --> 00:57:52,960 Speaker 3: a snake that can bite quickly, inject tons of venom 1004 00:57:53,000 --> 00:57:56,400 Speaker 3: really fast, and then run away. It has to sort 1005 00:57:56,400 --> 00:57:59,600 Speaker 3: of keep chewing and grinding to get more venom in there. 1006 00:58:00,360 --> 00:58:05,200 Speaker 3: And the evolutionary calculus has concluded that sometimes it makes 1007 00:58:05,240 --> 00:58:07,840 Speaker 3: sense for the lizard to have an instinct to bite 1008 00:58:07,840 --> 00:58:10,960 Speaker 3: and hold on and deliver more venom, even if that's 1009 00:58:11,000 --> 00:58:14,880 Speaker 3: going to keep the lizard initially exposed to the predator 1010 00:58:14,920 --> 00:58:19,560 Speaker 3: for longer. I think because a more venomated predatory animal 1011 00:58:19,600 --> 00:58:21,800 Speaker 3: is going to be less dangerous to you after the 1012 00:58:21,800 --> 00:58:22,760 Speaker 3: bite is released. 1013 00:58:23,480 --> 00:58:25,680 Speaker 2: You know, this is just pure guesswork on my part, 1014 00:58:25,720 --> 00:58:33,400 Speaker 2: but the fact that in some cases we have accounts 1015 00:58:33,520 --> 00:58:36,360 Speaker 2: of the lizard being killed while it's still attached, I 1016 00:58:36,400 --> 00:58:38,400 Speaker 2: wonder how many of those cases are going to be 1017 00:58:38,480 --> 00:58:42,520 Speaker 2: very specific a to humans and to tool using humans. 1018 00:58:42,520 --> 00:58:45,200 Speaker 2: Something that of course, a hate monster would not have 1019 00:58:45,920 --> 00:58:48,600 Speaker 2: evolved to cope with like if they have not evolved 1020 00:58:48,600 --> 00:58:51,840 Speaker 2: to cope with, say a pocket knife or I don't know, 1021 00:58:51,880 --> 00:58:54,280 Speaker 2: a revolver or something like that. Yeah. 1022 00:58:54,320 --> 00:58:56,000 Speaker 3: I think that's a good point. And I think if 1023 00:58:56,120 --> 00:58:59,840 Speaker 3: you just look more at the kinds of predator encounters 1024 00:58:59,840 --> 00:59:02,640 Speaker 3: the lizard is going to be having in its natural environment, 1025 00:59:03,200 --> 00:59:05,960 Speaker 3: what you generally get is just that the predator that 1026 00:59:06,000 --> 00:59:09,400 Speaker 3: has been bitten and venomated is going to be focused 1027 00:59:09,560 --> 00:59:12,320 Speaker 3: entirely on getting away from the lizard and taking care 1028 00:59:12,360 --> 00:59:15,400 Speaker 3: of its wounds. The motivation to eat the lizard by 1029 00:59:15,440 --> 00:59:19,840 Speaker 3: a natural predator is immediately deprioritized, and the lizard can 1030 00:59:19,960 --> 00:59:23,400 Speaker 3: escape if it survives, you know, the biting itself. 1031 00:59:23,800 --> 00:59:25,120 Speaker 2: Yeah, I just want to get it off of me, 1032 00:59:25,520 --> 00:59:27,520 Speaker 2: and then I want to get away from here. Yeah. 1033 00:59:27,600 --> 00:59:31,320 Speaker 3: So, and Beck argues that a major effect of the 1034 00:59:31,360 --> 00:59:36,680 Speaker 3: tenacious bite and the prolonged in venomation maybe to promote 1035 00:59:36,880 --> 00:59:41,840 Speaker 3: learning in predatory animals that it promotes, maybe in the 1036 00:59:41,920 --> 00:59:45,480 Speaker 3: one instance, a learning in that individual animal that it's 1037 00:59:45,480 --> 00:59:47,640 Speaker 3: not going to approach a lizard that looks like this again, 1038 00:59:47,680 --> 00:59:52,440 Speaker 3: and could also over evolutionary time by reducing the fitness 1039 00:59:52,600 --> 00:59:56,440 Speaker 3: of animals that have been bitten. It could produce evolutionary 1040 00:59:56,560 --> 01:00:01,120 Speaker 3: learning instinctual learning, where like animals, the predatory animals that 1041 01:00:01,200 --> 01:00:05,240 Speaker 3: avoid lizards that look like this are favored evolutionarily and 1042 01:00:05,280 --> 01:00:08,479 Speaker 3: thus eventually the predator species are less likely to mess 1043 01:00:08,520 --> 01:00:08,919 Speaker 3: with them. 1044 01:00:09,480 --> 01:00:13,480 Speaker 2: Okay, so it's an educational initiative. I'm the part of 1045 01:00:13,480 --> 01:00:14,320 Speaker 2: the Helo monsters. 1046 01:00:15,160 --> 01:00:17,360 Speaker 3: Anyway, it should go without saying at this point, but 1047 01:00:17,440 --> 01:00:19,560 Speaker 3: I think if there's one main takeaway from all this, 1048 01:00:19,760 --> 01:00:22,840 Speaker 3: it is just don't mess with helo monsters. This is 1049 01:00:22,880 --> 01:00:25,560 Speaker 3: not a lizard worth poking if you find it in nature, 1050 01:00:26,840 --> 01:00:30,120 Speaker 3: just you know, keep your distance, observe respectfully from afar. 1051 01:00:30,560 --> 01:00:33,520 Speaker 2: That's right, that's right, look at pictures and if you 1052 01:00:33,520 --> 01:00:35,400 Speaker 2: get a chance, if you do get a chance to 1053 01:00:35,400 --> 01:00:37,560 Speaker 2: see them in the wild, yes, do keep your distance. 1054 01:00:38,720 --> 01:00:42,360 Speaker 2: And if you see them at a zoo, well enjoy 1055 01:00:42,400 --> 01:00:45,200 Speaker 2: the treat of watching them. Probably sleep for an extended 1056 01:00:45,200 --> 01:00:48,720 Speaker 2: period of time. But yeah, still fabulous animals and I 1057 01:00:48,760 --> 01:00:53,200 Speaker 2: look forward to talking about them more in at least one, 1058 01:00:53,280 --> 01:00:56,880 Speaker 2: possibly two more episodes, because there's a lot more to cover. 1059 01:00:57,440 --> 01:01:01,640 Speaker 2: There are a lot of indigenous to about the HeLa 1060 01:01:01,680 --> 01:01:04,680 Speaker 2: monster like to get into. There are various sort of 1061 01:01:04,720 --> 01:01:08,440 Speaker 2: frontier myths about them as well that are pretty amusing 1062 01:01:08,480 --> 01:01:11,240 Speaker 2: and in some cases maybe insightful into the way humans 1063 01:01:11,240 --> 01:01:14,480 Speaker 2: were interacting with them. And then we're going to get 1064 01:01:14,480 --> 01:01:19,160 Speaker 2: into their role in pharmacology totally. All right, Well, in 1065 01:01:19,200 --> 01:01:22,000 Speaker 2: the meantime, I do write in if you have anything 1066 01:01:22,040 --> 01:01:24,240 Speaker 2: already you want to share with us about HeLa monsters 1067 01:01:24,440 --> 01:01:29,600 Speaker 2: field reports if you will. We're also open to any 1068 01:01:29,640 --> 01:01:32,520 Speaker 2: kind of info you want to send in regarding Helo 1069 01:01:32,560 --> 01:01:35,480 Speaker 2: monsters popping up in movies. There's a website that we 1070 01:01:35,520 --> 01:01:38,160 Speaker 2: always love to check out anytime that the subject of 1071 01:01:38,200 --> 01:01:40,800 Speaker 2: herbs and film comes up, and it's California herbs dot com. 1072 01:01:40,960 --> 01:01:42,760 Speaker 2: They have a whole section where you can look up. 1073 01:01:43,120 --> 01:01:45,040 Speaker 2: You can see what herbs have been in what movies, 1074 01:01:45,040 --> 01:01:46,960 Speaker 2: and what they were doing in them, how they were treated, 1075 01:01:47,640 --> 01:01:50,440 Speaker 2: and they have a listing for the HeLa monster, and 1076 01:01:50,480 --> 01:01:52,880 Speaker 2: it's an interesting selection of films. I was looking at this, 1077 01:01:53,000 --> 01:01:56,720 Speaker 2: and of course you have concerning Helo monsters and Beat 1078 01:01:56,720 --> 01:01:59,760 Speaker 2: of the Lizards. You have some pretty obvious inclusions there, 1079 01:01:59,800 --> 01:02:03,080 Speaker 2: but also like some classic westerns are just popping up 1080 01:02:03,080 --> 01:02:06,400 Speaker 2: in as part of the sort of background you know 1081 01:02:06,960 --> 01:02:09,840 Speaker 2: Frontier World. They pop up in Butch Casting The Sundance Kid, 1082 01:02:09,880 --> 01:02:12,640 Speaker 2: for example. No, I forgot about that. Yeah, what do 1083 01:02:12,720 --> 01:02:13,160 Speaker 2: they when? 1084 01:02:13,440 --> 01:02:14,760 Speaker 3: When do they show up in the movie? 1085 01:02:14,840 --> 01:02:18,439 Speaker 2: I think The Sundance Kid shoots a Helo monster. Oh yeah, 1086 01:02:18,520 --> 01:02:22,040 Speaker 2: yeah that. They show up in various older westerns to Florida, 1087 01:02:22,120 --> 01:02:24,439 Speaker 2: pache and then, of course there is the nineteen fifty 1088 01:02:24,520 --> 01:02:27,160 Speaker 2: nine film The Giant HeLa Monster, in which the HeLa 1089 01:02:27,200 --> 01:02:30,439 Speaker 2: Monster is played by a beaded lizard, so not even 1090 01:02:30,440 --> 01:02:33,360 Speaker 2: an actual HeLa monster. They couldn't get him. His asking 1091 01:02:33,400 --> 01:02:36,840 Speaker 2: price was too high. So do do write in if 1092 01:02:36,880 --> 01:02:39,760 Speaker 2: you have anything to share, Just a reminder of everyone 1093 01:02:39,760 --> 01:02:41,880 Speaker 2: out there.
