What are the enemies of walrus?

* Polar bears: Polar bears are the primary predators of walruses. They hunt walruses for their meat and fat, and they can kill a walrus with a single blow from their powerful paws.

* Killer whales: Killer whales are also predators of walruses. They hunt walruses in groups, and they use their echolocation to track their prey.

* Humans: Humans are the third major predator of walruses. Walruses are hunted for their meat, their tusks, and their fur.

* Climate change: Climate change is also a threat to walruses. As the Arctic ice melts, walruses are losing their habitat and their food sources.
