Any carnivorous animal (8)
I believe the answer is:
predator
'any carnivorous animal' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for predator that I've seen before include "Carnivorous animal - teardrop (anag)" , "Hunter" , "Marauding creature" , "eagle, say" , "Hunting creature" .)
