Meet the crabeater seal (Lobodon carcinophaga). It’s a charming specialized predator that lives on the coasts of Antarctica. It feeds almost exclusively on krill (90% of their diet) and sometimes cephalopods and antarctic fish.
Technique: The seal gobbles mouthfuls of krill and water drains through the spaces created by its teeth.
Crabeaters have little food competition, but as pups they are heavily preyed upon by leopard seals.
