Slow-moving tree dweller (5)

I believe the answer is:
sloth
'slow-moving tree dweller' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sloth that I've seen before include "Sluggish creature" , "One hangs a lot" , "Arboreal animal" , "Inertia" , "Idleness" .)
