The crabeater seal is a marine mammal that lives in cold waters around Antarctica. It has special teeth that work like a sieve and help catch small krill crustaceans.
The crabeater seal differs from other seals with its filter teeth, which allow it to eat huge amounts of krill. It is very important for Antarctic nature because it links krill with larger predators such as orcas and leopard seals.
