00:00:02,040 --> 00:00:07,080
Speaker 1: Welcome to brain Stuff from How Stuff Works, Hey, brain Stuff,

2
00:00:07,120 --> 00:00:10,560
Speaker 1: Lauren Vogel Bam here. Sloths are known for their incredibly

3
00:00:10,600 --> 00:00:13,960
Speaker 1: slow moving natures, but it turns out that such sluggishness

4
00:00:14,000 --> 00:00:17,240
Speaker 1: also carries over into their bathroom habits, so much so

5
00:00:17,320 --> 00:00:20,400
Speaker 1: that they only defecate every five to seven days on average,

6
00:00:20,560 --> 00:00:22,720
Speaker 1: and actually lose up to one third of their body

7
00:00:22,760 --> 00:00:25,640
Speaker 1: weight in a single movement. The stool is pushed out

8
00:00:25,640 --> 00:00:28,600
Speaker 1: and one fell swoop so impressive that horrified and or

9
00:00:28,680 --> 00:00:33,680
Speaker 1: transfixed bystanders can watch the animals abdomen shrink. We spoke

10
00:00:33,800 --> 00:00:36,520
Speaker 1: via email with Sarah Kennedy, co founder of the Sloth

11
00:00:36,560 --> 00:00:40,879
Speaker 1: Conservation Foundation based in the United Kingdom. She said, if

12
00:00:40,920 --> 00:00:43,480
Speaker 1: you've ever seen a sloth pooh, you could only ever

13
00:00:43,520 --> 00:00:47,240
Speaker 1: describe it as pure bliss. They tip their heads back

14
00:00:47,320 --> 00:00:51,760
Speaker 1: and smile. But the week long delay between bowel movements

15
00:00:51,800 --> 00:00:54,760
Speaker 1: is not even the strangest thing about sloth pooping habits.

16
00:00:55,280 --> 00:00:58,800
Speaker 1: You see. Sloughs are arboreal creatures, which means they live, work,

17
00:00:58,880 --> 00:01:02,440
Speaker 1: and play high up in the trees. They're chosen habitats

18
00:01:02,440 --> 00:01:05,280
Speaker 1: are the rain and cloud forests of Central and South America.

19
00:01:05,880 --> 00:01:09,199
Speaker 1: Most other arboreal animals like monkeys poop from the trees,

20
00:01:09,319 --> 00:01:13,119
Speaker 1: but not sloths. Instead, they make a slow descent from

21
00:01:13,120 --> 00:01:15,440
Speaker 1: the canopy to do their business at the base of

22
00:01:15,480 --> 00:01:19,040
Speaker 1: the trees, and this despite the fact that it's quite perilous.

23
00:01:19,400 --> 00:01:22,399
Speaker 1: Kennedy said, this behavior puts them threat to a lot

24
00:01:22,440 --> 00:01:24,920
Speaker 1: of predators like jungle cats, and wastes a lot of

25
00:01:24,920 --> 00:01:28,640
Speaker 1: their precious energy, which they don't have much of. It

26
00:01:28,720 --> 00:01:31,360
Speaker 1: turns out that more than half of all sloth deaths

27
00:01:31,360 --> 00:01:34,839
Speaker 1: occur during potty time, when these creatures are so vulnerable

28
00:01:34,840 --> 00:01:40,040
Speaker 1: to predators. The process comes at a serious price. Zoologist

29
00:01:40,080 --> 00:01:43,320
Speaker 1: and Sloth Conservation Foundation founder Becky Cliff wrote in a

30
00:01:43,360 --> 00:01:47,120
Speaker 1: blog post a slot's entire lifestyle is based around avoiding

31
00:01:47,120 --> 00:01:50,560
Speaker 1: detection and using as little energy as possible. It takes

32
00:01:50,560 --> 00:01:53,320
Speaker 1: a sloth an entire month to digest just one leaf,

33
00:01:53,640 --> 00:01:55,880
Speaker 1: meaning they don't have much wiggle room when it comes

34
00:01:55,920 --> 00:02:00,520
Speaker 1: to expending energy. The laborious process of going up and

35
00:02:00,600 --> 00:02:03,920
Speaker 1: down the tree is compounded by the actual pooping process.

36
00:02:04,440 --> 00:02:06,520
Speaker 1: Sloths do a little dance at the base of the

37
00:02:06,520 --> 00:02:08,919
Speaker 1: tree to create a hole for the feces, and then

38
00:02:08,960 --> 00:02:11,480
Speaker 1: shake their hind quarters once more to cover it up.

39
00:02:12,080 --> 00:02:16,080
Speaker 1: This process requires you guessed it plenty of precious energy.

40
00:02:16,919 --> 00:02:19,280
Speaker 1: A lot of theories have been put forth about why

41
00:02:19,360 --> 00:02:21,880
Speaker 1: sloths feel the need to expend so much effort and

42
00:02:21,960 --> 00:02:25,720
Speaker 1: expose themselves to so much danger just to toilet. One

43
00:02:25,760 --> 00:02:28,880
Speaker 1: theory is it sloth moths, which live in sloth hair,

44
00:02:29,200 --> 00:02:32,040
Speaker 1: actually lay their eggs in the feces during the long

45
00:02:32,160 --> 00:02:35,679
Speaker 1: poop process. Then once they hatch and mature in their

46
00:02:35,720 --> 00:02:38,760
Speaker 1: carefully prepared environment, they fly up to take residence in

47
00:02:38,760 --> 00:02:42,560
Speaker 1: the host sloths fur. Many experts, though, are skeptical of

48
00:02:42,600 --> 00:02:46,440
Speaker 1: this explanation because the sloths don't particularly benefit from the behavior,

49
00:02:46,720 --> 00:02:51,440
Speaker 1: and nature isn't generally known for its selfless generosity. More likely,

50
00:02:51,520 --> 00:02:55,040
Speaker 1: but as yet unproven, is that the strange behavior comes

51
00:02:55,080 --> 00:02:58,200
Speaker 1: back to reproduction, as it so often does when living

52
00:02:58,240 --> 00:03:02,760
Speaker 1: things are involved. Explained, the main reason is probably so

53
00:03:02,800 --> 00:03:06,000
Speaker 1: that other sloths can find them, a particularly males looking

54
00:03:06,040 --> 00:03:09,200
Speaker 1: for females. Usually the slaws come down every five to

55
00:03:09,200 --> 00:03:12,080
Speaker 1: seven days, but when females are in heat it's every day,

56
00:03:12,400 --> 00:03:16,880
Speaker 1: so it's likely to be mostly to do with reproduction. Indeed,

57
00:03:16,919 --> 00:03:19,240
Speaker 1: it appears at sloth poop says a lot more about

58
00:03:19,240 --> 00:03:22,919
Speaker 1: the animal than merely what they've been nothing on. Cliff wrote,

59
00:03:23,280 --> 00:03:25,919
Speaker 1: pheromones present in the uinin feces can provide a lot

60
00:03:25,960 --> 00:03:29,720
Speaker 1: of important information about the individual animal. If the sloths

61
00:03:29,800 --> 00:03:32,760
Speaker 1: just let everything go from the canopy, these messages would

62
00:03:32,800 --> 00:03:36,080
Speaker 1: be easily lost. We have heaps of data showing some

63
00:03:36,160 --> 00:03:39,160
Speaker 1: really interesting patterns between a female's estra cycle and the

64
00:03:39,240 --> 00:03:43,760
Speaker 1: patterns of defecation. We'll be waiting patiently for the answer

65
00:03:43,800 --> 00:03:48,119
Speaker 1: to this mystery, because if observing sloss teaches anything, it's patients.
