Cave bears, dire wolves, and prehistoric humans
Polar bears are apex predators. Only humans regularly hunt and kill them.
In the wild, adult black bears are typically not preyed upon by other animals. However, young black bears may be targeted by predators such as wolves, mountain lions, and occasionally other bears.
The orca is the only animal that occasionally preys on swimming polar bears.
The bear is what is known as an apex predator; it preys upon other animals but no other animal preys upon the bear (not counting parasites; bears can have ticks, for example, which eat part of the bear, but not the whole bear). Of course, bears do not live forever, and when they die, lots of other animals can eat them. But no animal kills bears to eat them, not counting humans (bear paws are considered a delicacy in China).
