About International Sloth Day
International Sloth Day, started in 2010 by the AIUNAU conservation foundation in Colombia, is celebrated on October 20th. Sloths move so slowly that algae grows in their fur — a feature, not a bug, providing camouflage. The day supports rainforest conservation and rescue centers, and gives everyone an excuse to slow down.
