Swamp creature, informally (5)

I believe the answer is:

gator

(Other definitions for gator that I've seen before include "dangerous reptile shortly" , "One taking snaps" , "Informal American term for semi-aquatic reptile" , "Crocodilian (informal)" , "US snapper" .)

I've seen this clue in The New York Times.
