Animal throat (3)
I believe the answer is:
maw
'animal throat' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for maw that I've seen before include "Jaws or gullet of a voracious animal" , "Gaping mouth of voracious animal" , "Mouth (animal's)" , "Crop of an animal" , "gulf" .)
