Description

The clown knifefish is a large featherback (Notopteridae) from South Asia. The species grows to about 1.2 metres and has a strongly laterally compressed, knife-shaped body with a high back, a long, undulating anal fin merging with the tail and often a row of eyespots along the lower back. It inhabits rivers, lakes, beels, reservoirs, canals and ponds in the lowlands. As a nocturnal predator it hunts aquatic insects, molluscs and small fishes; it can breathe air with its swim bladder. Owing to fishing and habitat loss the species is considered near threatened. It is harmless to humans.
