Marine Mammals:
* Polar bears: Polar bears are the apex predator of the Arctic and rely heavily on seals for food.
* Orcas (killer whales): Orcas are highly intelligent and adaptable predators that can hunt seals in various environments, including open water, ice floes, and even on land.
* Leopard seals: These large seals are specialized seal hunters, particularly in the Antarctic.
Other Predators:
* Great white sharks: Great whites are known to prey on seals, especially in coastal waters.
* Greenland sharks: These slow-moving sharks are ambush predators that can consume seals.
* Walruses: While mainly bottom feeders, walruses can occasionally prey on young seals.
Note: The specific predators of seals vary depending on the species of seal and the region they inhabit.
