The Redfin trahira (Erythrinus erythrinus) is a freshwater fish of the family Erythrinidae that grows up to 20 cm.
Description
Erythrinus erythrinus is an elongate freshwater predator of the family Erythrinidae, widespread in tropical South America, especially the Amazon and Orinoco basins. It grows to about 20 cm and has a cylindrical, brownish-red body with a large, small-toothed mouth. Living in slow-moving and still waters, it can gulp air with its swim bladder, allowing it to survive oxygen-poor water and even short journeys over land between pools. A nocturnal predator, it hunts small fishes, insects and crustaceans. The species is only rarely eaten.
