However, there are a few threats:
* Polar bears: They are the main predator of walruses, especially young ones. They will sometimes prey on adult walruses, but this is more difficult due to their size and strength.
* Orcas (Killer Whales): Orcas can hunt walruses, particularly if the walruses are hauled out on land or ice. They may target calves and weaker individuals.
* Other threats: Some walrus calves may fall prey to foxes or wolves, but these are not significant threats to the population as a whole.
It's important to remember that human activities like hunting and climate change are also major threats to walrus populations.
