Description

The trahira or wolf fish is a stocky, cylindrical predator of the family Erythrinidae reaching about 65 cm. The brown, mottled body has a large head and a broad mouth full of sharp teeth. The species can gulp air with its muscular swim bladder and so survive in warm, oxygen-poor water. It comes from the fresh water of Central and South America and lives in slow water of rivers, lakes, ponds and swamps. As an ambush predator it lies still among plants and strikes fiercely at mainly other fish, supplemented with crustaceans and insects. The male guards a nest pit with eggs and young. It is a valued food and sport fish that bites fiercely when handled.
