Arctic carnivore (5,4)
I believe the answer is:
polar bear
'arctic carnivore' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for polar bear that I've seen before include "Beast of the Arctic" , "Arctic-dwelling mammal" , "Largest carnivorous land mammal" , "big brute" , "Arctic mammal" .)
