Scavengers are animals that feed on carrion or refuse, rather than kill their own prey.
Hyenas, vultures, and raccoons are all scavengers. Other animals such as owls and rats can act as scavengers, although they may be carnivores or omnivores.
"Bottom feeders" such as catfish and some crabs are scavengers.
Some other animals that can be scavengers are:
Shark (there are many)
Maggots (Fly Larvae)
Flathead(a fish in Australia)
Heksia (found in Africa)Vultures, carrion crows
