The Insane Biology of: Sloths

I watched this at .25x speed out of respect.

As Sam O Nella once said Sloths were the creatures that when asked to choose between being a plant or an animal said "Both"

"their ongoing survival seems like an actual mistake" I felt that

Everyone who eats avocados owes a debt of gratitude to ancient giant sloths. They were big enough to eat the avocados whole, stone and all. Then the stone passed through their digestive system until it was deposited with a helpful amount of manure. Thus giant sloths spread avocados around and allowed them to grow and flourish.

Biologist watching a sloth moving in a single branch a whole day for science: THIS IS EPIC

As a Costa Rican tour guide I ask that you take a moment to help us shed light on a serious issue occurring here: in La Fortuna of San Carlos (very popular tourist location) some private land owners are setting up “Sloth parks” where they are forcibly taking sloths from their place in the wild so that they can put them in their “park”. We have contacted the authorities but very little is being done as evidence is difficult to come by (there are rumors that homeless or drug-addicted citizens are paid to turn in the sloths in bags, but the declining populations of sloths in the wild make it clear that rumor or not, something is going on as they have disappeared far too quickly for it to be caused by natural selection, etc.) There is even a video of our current president with an “expert” saying that there is no evidence that these parks are doing anything illegal, but it is clear to the local guides as it is unnatural for a group of sloths to all reside in one small location (and mysteriously, all of the sloths typically found in the area have almost completely disappeared, when we would often see at least one, two, or three per day along the forest edge by the road). Please help by posting and spreading the word on social media or whatever you use, we want to put pressure on the government to take this issue seriously before it drastically affects the sloth population.

The "Insane Biology" series is top notch. You're an incredible teacher and filmmaker. :)

Sloths are like the perfect gym bros, strong, yet humble

I would love to see the biology of the goblin shark

That's so interesting to see the cycle between sloths and moths! Our crew filmed a project that tries to understand moths' behaviour and how they evolved to evade bats!

I had no idea I'd be staying for the whole video! My respect for the Sloth has increased massively!

19:22 That itching is the fastest movement of sloth I have ever seen

This was an insightful presentation on the biology of the Sloth! They are incredible animals that have found a unique way to survive our brutal environment! Thank you for sharing this amazing video, and educating people on the fantastic animals we have on our planet we call Earth.

My "spirit animal" never looked so good. Thanks, guys.

The sloth temperature control is the most insane of your fascinating insane biology videos. Also the Henry Rollins poster in Mike Butcher's office.

Hello!! I'm from Costa Rica and I study Geology on the University of Costa Rica where there are several sloth families living around the campus, I have seen them even doing the hilarious poop dance you were talking about. I really love your channel and it always amazes me your story-telling technique. Hope that you have a wonderful time on our country!

Seriously thank you for your work! It makes me realise that animals I thought I know about are the ones I know the least about.

Slaking’s 160 Base Attack Stat makes all the more sense now 😳

Can we take a moment to appreciate the quality of the video. Hats off

Thanks for all the work you guys put in!! Defo my top 5 favourite channels on YouTube ❤️
