International Sloth Day – October 20, 2019

Sun Oct 20

Hang out and celebrate International Sloth Day this October 20. Sloths are slow moving mammals often found in Central and South America. The two major types are the two-toed and three-toed sloths. Although sloths look like some kind of furry bear/monkey, their closest relatives are actually anteaters and armadillos. This international holiday was first created by the foundation AIUNAU, a program dedicated to the conservation and rehabilitation of wildlife in Columbia. AIUNAU first started working with sloths in 1996, and has worked to promote their cause ever since.

International Sloth Day - History


​Sloth fossils discovered

​Researchers found sloth fossils off a coastal desert in Peru and discovered they belonged to a group of sloths called Thalassocnus, who were semiaquatic and lived alongside whales and crocodiles.


Prehistoric proof

​Smithsonian curator Remington Kellogg found a substance at the Grand Canyon that turned out to be 100,000-year-old sloth fecal matter. This sample has since allowed researchers to learn about past diet, and give insight into the environment in which they lived.


Presidential sloth

Thomas Jefferson was involved in the discovery of an extinct sloth species. He received a gift fossil from a friend and submitted a research paper.

​5 Facts About The Daily Life Of A Sloth

  1. They're s-l-o-w

    ​Because sloths have a slow metabolic process they usually only relieve themselves once per week.

  2. ​Just hanging around

    ​Sloths are arboreal animals, meaning they spend most of their lives in trees.

  3. ​Camouflage at a whole new level

    ​A sloth’s fur hosts a vast ecosystem of moths, bugs, and algae — which taints their furs green and is used as camouflage in the trees.

  4. Are you looking at me?

    ​Three–toed sloths are able to turn their heads nearly 360 degrees.

  5. Aging gracefully

    When sloths survive possible poachers and captors, they can live anywhere between 10 and 30 years!

Why We Love International Sloth Day

  1. They can get aggressive — if necessary.

    Although sloths have peaceful demeanors, wild sloths can be aggressive and bite very hard. If caught by a predator on land you are likely to hear a sloth hissing, or shrieking. Visitors at a sloth nursery should not get too close.

  2. Sloths are master of zen

    Sure, sloths have their moments, but they are so mesmerizing to watch as they rest in trees and stay serene for what seems an eternity . It is no wonder sloths are highly popularized in media.

  3. They are downright adorable

    It is nearly impossible to look at sloths and not gush. Their fur is thick and soft — and their eyes are big pools of warmth. From their casual vibe, to their permanent smiles, they beam beauty.
