Description

The giant trahira is a large predatory characin of the trahira family (Erythrinidae) from the north of South America. The species grows to about one metre and has a robust, cylindrical, dark body with a large head and a broad mouth full of sharp teeth. It inhabits rivers, creeks and pools, often in quiet water. As an ambush apex predator it lies motionless in wait and seizes fishes and other prey. Trahiras can endure oxygen-poor water for short periods with an accessory air-breathing ability. The giant trahira is an important food fish. The powerful jaws with sharp teeth can give a nasty bite; handle a caught specimen with care.
