Description

The giant trahira or aimara is a large, muscular predator of the family Erythrinidae reaching about 1 metre and the largest of its family. The cylindrical, brown-marbled body has a broad, blunt head and a mouth full of large, sharp teeth. The species comes from the Amazon and Orinoco basins and the Guianas of northern South America and lives in flowing rivers, rapids and pools. As a powerful ambush predator it lies still and strikes fiercely at mainly other fish, supplemented with crustaceans. The male guards a nest pit with eggs and young. For its size and strength the aimara is one of the most prized freshwater sport fish of South America; it bites fiercely and must be handled with care.
