Scavengers

There are lots of garbage scavengers in Algiers.

Jackals are scavengers.

The genetic evidence comes from an unusually well-preserved polar bear jawbone with a canine tooth still attached to it — a rare find because most polar bear carcasses are consumed by scavengers or sink to the sea bottom. The DNA mapped from the jawbone is the earliest mammalian genome ever sequenced.

Lions are scavengers, among other things.
