A genus of two-toed sloths found in Central and South America.
From Greek 'chole' (bile) + 'lepus' (hare). The name references the sloth's slow, lethargic movements, which early naturalists associated with excess bile and melancholy humors.
Despite its scientific name meaning 'bile-hare,' the choloepus sloth has nothing to do with bile—it's just that medieval medicine blamed slow movement on an imbalance of bile, so early taxonomists kept using bile references for slow creatures!
