A Crabeater seal skull (Spanish: Foca Cangrejera, scientific name: Lobodon carcinophaga) shows finely-lobed teeth adapted to filtering krill. Contrary to their name, Crabeater seals don't eat crabs (which are not found in their coastal Antarctica home); instead, they primarily eat krill, a tiny crustacean. Crabeater seals are the most numerous large species of mammal on Earth, after humans and cattle.
