Primary Predators:
* Polar Bears: These are the main predators of walruses, particularly young calves. They are powerful and agile hunters, and their large size and strength give them an advantage.
Secondary Predators:
* Orcas (Killer Whales): Orcas are known to hunt walruses, especially in areas where walruses haul out on land. They are clever and coordinated hunters, and their ability to swim quickly and efficiently makes them formidable predators.
* Other Large Predators: There have been rare instances of other large predators like brown bears and wolves hunting walruses, but these are not common occurrences.
Other Threats:
* Human Activity: Human activities like hunting and habitat destruction pose a significant threat to walruses.
It's important to remember that walruses are large and powerful animals, and they are capable of defending themselves against predators. However, they are vulnerable when they are on land or in shallow water, and they are particularly vulnerable when they are young or injured.
