What eats fish?

Fish is a staple in many creatures' diet. Fish are eaten by larger fish, by aquatic mammals, seabirds, and mammals such as bear and man as a regular part of their diet.

Clearly, dolphins, eels, sharks, seals, walruses, penguins, seal lions, and killer whales prey on fish, too. Eagles and raptors typically eat fish as a regular part of their diets.
