Heading off Moroccan wild animal (7)
I believe the answer is:
raccoon
'animal' is the definition.
(I've seen this before)
'heading off moroccan wild' is the wordplay.
'heading off' means to remove the first letter.
'wild' indicates anagramming the letters.
'moroccan' with its first letter taken off is 'oroccan'.
'oroccan' anagrammed gives 'RACCOON'.
(Other definitions for raccoon that I've seen before include "Smallish American animal" , "wild animal" , "US mammal with a fox-like face" , "US ring-tailed mammal" , "Mammal with pointed muzzle and long tail" .)
