Cold-blooded creature (7)

I believe the answer is:

reptile

'cold-blooded creature' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for reptile that I've seen before include "Cold-blooded vertebrate" , "Unpleasant character" , "Cold-blooded beast" , "Malignant creature" , "Snake or croc?" .)

I've seen this clue in the Evening Standard and The Mirror.
