Long-necked creature (7)
I believe the answer is:
giraffe
'long-necked creature' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for giraffe that I've seen before include "Tallest living quadruped" , "Fire fag at the animal" , "Animal once known as a camelopard" , "Tallest mammal" , "Long-necked ruminant" .)
