Serengeti scavenger (5)
I believe the answer is:
hyena
'serengeti scavenger' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hyena that I've seen before include "Beast" , "Carnivorous mammal" , "Carrion-eating, dog-like animal" , "Dog-like animal with laughter-like howl" , "Dog-like African carnivore" .)
