00:00:01,920 --> 00:00:07,040
Speaker 1: Welcome to brain Stuff production of iHeart Radio. Hey brain Stuff,

2
00:00:07,120 --> 00:00:10,920
Speaker 1: Lauren bog Obam here. The giant squid is a carnivorous

3
00:00:10,960 --> 00:00:13,880
Speaker 1: invertebrate that weighs over four hundred and forty pounds or

4
00:00:13,960 --> 00:00:18,799
Speaker 1: two and measures around thirty three ft or ten meters long. Yes,

5
00:00:18,880 --> 00:00:21,000
Speaker 1: it can be as long as a school bus and

6
00:00:21,040 --> 00:00:23,439
Speaker 1: has eyes the size of dinner plates, along with a

7
00:00:23,520 --> 00:00:28,680
Speaker 1: sharp beak. In short, it's a little disconcerting. Perhaps more

8
00:00:28,760 --> 00:00:31,479
Speaker 1: disconcerting is the fact that these wild creatures, which have

9
00:00:31,760 --> 00:00:34,400
Speaker 1: rarely ever been spotted alive, have been popping up in

10
00:00:34,560 --> 00:00:38,440
Speaker 1: videos in recent years, very much alive and very very large.

11
00:00:39,280 --> 00:00:42,240
Speaker 1: Before two thousand four, they had only been found as carcasses,

12
00:00:42,320 --> 00:00:46,120
Speaker 1: washed up on beaches or captured by fishermen. So what's

13
00:00:46,159 --> 00:00:48,760
Speaker 1: going on under the sea is a rash of giant

14
00:00:48,840 --> 00:00:51,839
Speaker 1: squid sightings and indication that these sea giants are taking

15
00:00:51,840 --> 00:00:56,080
Speaker 1: over the waves. In a word, no, but the sightings

16
00:00:56,080 --> 00:01:00,440
Speaker 1: do indicate technology is advancing in exciting new ways. We

17
00:01:00,520 --> 00:01:04,760
Speaker 1: spoke Edith Whittard, PhD uh, the CEO and Senior scientist

18
00:01:04,800 --> 00:01:09,320
Speaker 1: of Florida's Ocean Research and Conservation Association, Incorporated. She said

19
00:01:09,880 --> 00:01:12,399
Speaker 1: it hasn't really been a rash of giant squid sightings.

20
00:01:12,440 --> 00:01:14,520
Speaker 1: There have only been two times that giant squid have

21
00:01:14,600 --> 00:01:18,080
Speaker 1: been filmed in the deep sea. Both times the animals

22
00:01:18,080 --> 00:01:20,120
Speaker 1: were spotted with help from a camera system and an

23
00:01:20,160 --> 00:01:23,560
Speaker 1: optical lure that wid are developed to help researchers explore

24
00:01:23,600 --> 00:01:26,679
Speaker 1: the creatures of the deep sea without scaring them away.

25
00:01:27,160 --> 00:01:30,720
Speaker 1: The camera system is called Medusa. Medusa is unlike any

26
00:01:30,760 --> 00:01:33,760
Speaker 1: recording device used before because it emits a red light

27
00:01:33,880 --> 00:01:36,880
Speaker 1: that's invisible to most creatures living in the midnight zone.

28
00:01:37,200 --> 00:01:40,120
Speaker 1: That's the expanse of pitch black water about three thousand,

29
00:01:40,160 --> 00:01:43,360
Speaker 1: three hundred feet or a thousand meters below the ocean surface.

30
00:01:44,120 --> 00:01:47,920
Speaker 1: Then there's the optical lure and electronic jellyfish that accompanies

31
00:01:47,960 --> 00:01:50,920
Speaker 1: Medusa down below the waves to help draw creatures towards

32
00:01:50,960 --> 00:01:54,000
Speaker 1: the camera with an innovative method that takes inspiration from

33
00:01:54,040 --> 00:01:58,600
Speaker 1: animals natural cues called an e jelly wid are explained.

34
00:01:59,000 --> 00:02:02,520
Speaker 1: The e jelly image hates the bioluminescent burglar alarm display

35
00:02:02,560 --> 00:02:06,720
Speaker 1: of a common deep sea jellyfish. Bioluminescent burglar alarms are

36
00:02:06,760 --> 00:02:09,600
Speaker 1: like a scream for help using light. Their last ditch

37
00:02:09,639 --> 00:02:11,560
Speaker 1: effort of prey that are caught in the clutches of

38
00:02:11,560 --> 00:02:14,480
Speaker 1: a predator to attract the attention of a bigger predator

39
00:02:14,639 --> 00:02:17,280
Speaker 1: that may attack their attacker and thereby afford them an

40
00:02:17,320 --> 00:02:21,560
Speaker 1: opportunity for escape. Until just fifteen years ago, the only

41
00:02:21,600 --> 00:02:24,520
Speaker 1: facts known about giants squid were gathered from their massive

42
00:02:24,520 --> 00:02:28,280
Speaker 1: dead bodies, since live ones had never been seen. Then,

43
00:02:28,440 --> 00:02:30,920
Speaker 1: in two thousand four, the first live images of a

44
00:02:30,919 --> 00:02:34,240
Speaker 1: giant squid were captured, and the first video of a

45
00:02:34,240 --> 00:02:37,600
Speaker 1: giant squid emerged thanks to Medusa capturing a specimen swimming

46
00:02:37,639 --> 00:02:41,560
Speaker 1: off of Japan's Okasawara Archipelago. It wasn't until June of

47
00:02:41,560 --> 00:02:45,000
Speaker 1: twenty nineteen that another Medusa shot giant squid video came

48
00:02:45,000 --> 00:02:47,720
Speaker 1: to light, this time of a roughly ten foot long

49
00:02:47,760 --> 00:02:51,200
Speaker 1: that's three meters young swimmer in US waters around the

50
00:02:51,200 --> 00:02:55,040
Speaker 1: e Gulf of Mexico. June twenty nineteen marked the fifth

51
00:02:55,040 --> 00:02:58,640
Speaker 1: deployment of Medusa on this particular expedition, and when Winter

52
00:02:58,760 --> 00:03:01,880
Speaker 1: and her team examined the video, they saw undeniable footage

53
00:03:01,880 --> 00:03:04,760
Speaker 1: of a long, tentacled creature reaching out for the e jelly.

54
00:03:05,280 --> 00:03:07,480
Speaker 1: It's hard to tell exactly how big it was because

55
00:03:07,520 --> 00:03:11,240
Speaker 1: it was heading straight towards the camera. All these years

56
00:03:11,240 --> 00:03:14,760
Speaker 1: of underwater chasing begs the question why are these animals

57
00:03:14,800 --> 00:03:18,080
Speaker 1: so camera shy in the first place? Witter said, the

58
00:03:18,120 --> 00:03:21,440
Speaker 1: giant squid has been elusive because our standard methods of exploration,

59
00:03:21,560 --> 00:03:24,760
Speaker 1: using platforms with bright lights and noisy thrusters, has been

60
00:03:24,800 --> 00:03:27,720
Speaker 1: scaring it away. The only reason we even knew giant

61
00:03:27,800 --> 00:03:30,440
Speaker 1: squid existed is because they happen to float when they die.

62
00:03:30,880 --> 00:03:33,400
Speaker 1: So dead and dying specimens have been seen in photographed

63
00:03:33,400 --> 00:03:36,320
Speaker 1: at the surface. How many other animals are there living

64
00:03:36,320 --> 00:03:38,160
Speaker 1: in the deep sea that we don't know about because

65
00:03:38,160 --> 00:03:40,480
Speaker 1: we've been scaring them away and they don't happen to

66
00:03:40,480 --> 00:03:43,600
Speaker 1: float when they die, A good and perhaps even more

67
00:03:43,680 --> 00:03:52,960
Speaker 1: disconcerting question. Indeed. Today's episode was written by Michelle Constantonowsky
