Description

The butter catfish is a sheatfish (Siluridae) from South Asia. The species has a laterally compressed, scaleless body with a long anal fin, a strongly reduced or absent dorsal fin and two pairs of barbels; younger animals have a blotch near the shoulder. Adults live in quiet, shallow, often turbid water of sandy streams, rivers and tanks. As a nocturnal predator it hunts small fishes, crustaceans and insects. Owing to overfishing the species is considered near threatened. The pectoral fin spines can give a painful puncture wound when handled.
