Description

The bronze featherback is a freshwater fish of the featherback family (Notopteridae) from South and Southeast Asia. The species grows to about 60 cm and has a strongly compressed, knife-shaped body with a long anal fin that merges seamlessly into the caudal fin; the dorsal fin is greatly reduced. It lives in clear streams, lakes, canals and floodplains and sometimes enters brackish water. As a nocturnal predator it hunts small fishes and invertebrates and can breathe air with a modified swim bladder. The species is fished commercially and is harmless to humans.
