Ursine animals (5)
I believe the answer is:
bears
'ursine animals' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for bears that I've seen before include "Carries" , "Massive mammals with shaggy coats" , "Big animals" , "Large animals, polar or brown" , "Large animals, polar or grizzly" .)
