What is the relationship between the leopard seals and crabeater seals?

Leopard seals and crabeater seals are both members of the family Phocidae, commonly known as true seals, and are found in the Antarctic region. While they share similar habitats and dietary habits, crabeater seals primarily feed on krill, whereas leopard seals are apex predators that prey on a variety of marine animals, including seals, penguins, and fish. Their differing diets and behaviors create a competitive dynamic in their shared ecosystem, but they do not directly compete for food due to their specific dietary preferences. Despite these differences, both species play vital roles in the Antarctic marine ecosystem.
