A handy guide to the changing body of knowledge about sloth biology and sloth behavior. Includes the surprise (discussed here before in an interview with a zoologist from the Smithsonian's National Zoo) that supposedly slow sloths that move quite quickly under certain circumstances.


  1. I recall reading in one of naturlist Gerald Durrell’s (brother of novelist Lawrence Durrell) books his account of trying to transport a sloth to a zoo, and finding that the normally slow animal had lightning speed with its claws when upset.

  2. “…sloths that move quite quickly under certain circumstances”  I think I saw that video!  They move fast when they are chased by Samurai, right?  Or was it Ninjas?
