Slow, gentle and famously relaxed, sloths have become internet favorites. International Sloth Day, on October 20, celebrates these unique mammals and raises awareness of the threats they face, such as deforestation and the illegal pet trade. Sloths live in the rainforests of Central and South America and spend most of their lives hanging upside down in trees.
History of International Sloth Day
Sloths have a long evolutionary history. Giant ground sloths, some as large as elephants, roamed the Americas until about 10,000 years ago.
Today, there are six species of sloths, divided into two-toed and three-toed sloths. They move slowly to conserve energy, as their diet of leaves provides little nutrition. Algae grows in their fur, helping them blend in with trees.
International Sloth Day was established in 2010 by the AIUNAU Foundation in Colombia, which rescues and rehabilitates sloths and other animals.
Sloths spend about 90 percent of their lives hanging upside down. They eat, sleep and even give birth in trees, coming down only about once a week to go to the bathroom, which is when they are most vulnerable to predators. Surprisingly, sloths are good swimmers and can hold their breath for a long time.
Why International Sloth Day Matters
Sloths play a role in rainforest ecosystems, hosting algae, insects and other organisms in their fur.
They face threats from deforestation, power lines, roads and the illegal pet trade.
The day encourages people to support rainforest conservation and avoid wildlife tourism that harms sloths, such as holding them for photos.
Sloths have also become ambassadors for rainforest conservation. Their popularity on social media has raised awareness of deforestation in Central and South America. Supporting rescue centers that rehabilitate injured sloths and protecting forest corridors that let sloths move safely between trees can help these animals survive.
