Are leopard seals apex predators?
Leopard seals are an important Antarctic apex predator that can affect marine ecosystems through local predation.
Why do leopard seals eat other seals?
Leopard seals are the only seal species known to actively prey on other seals, taking pups of crabeater, Weddell, Ross, southern elephant and Antarctic fur seals. Extensive predation by leopard seals is thought to play a substantial role in preventing the growth of some fur seal populations.
Do crabeater seals eat cod?
There are stealthy weddell seals that can dive to depths of 600 metres for cod, their favourite food. … But the most remarkable thing about the crabeater seal is its lobed teeth, unlike any other in the animal kingdom. They look like chainsaws and act like sieves, straining out krill from seawater.

Do leopard seals eat sharks?
While multiple diet studies have been conducted before, none ever found the species predating on chondrichthyans. The study, led by Krista van der Linde of leopardseals.org, suggests that leopard seals are part of an exclusive club of marine predators that prey on sharks.
How fast are leopard seals?
A Leopard Seal can travel at speeds of up to 18 miles per hour.
What is the difference between a sea lion and a leopard seal?

Why do crabeater seals eat krill?
Krill comprise 90 percent of the crabeater seal’s diet, with cephalopods and Antarctic fish making up the rest of their diet. While many Antarctic birds and mammals eat krill, crabeater seals are krill specialist feeders, with a unique adaptation for filtering the tiny crustaceans from seawater.
How do crabeater seals stay warm?
Since crabeater seals live in a habitat with extremely cold temperatures, they stay warm with the assistance of a thick layer of fat in their bodies which is known as blubber. This layer of fat traps warmth in their bodies and is one of the many crabeater seal adaptations known to scientists.
What adaptations do crabeater seals have?
Crabeater Seals have a unique adaptation for feeding – they have evolved a sieve-like tooth structure that filter krill, somewhat like the baleens on Baleen Whales. They suck in water containing krill, close their jaws, and then force the water back out between their specialized teeth, trapping the krill inside.
