Description

The squarehead catfish is a remarkable bottom catfish from South Asia, occurring in India, Bangladesh, Nepal, Myanmar, Malaysia and Indonesia. It grows to about 20 cm and has a broad, strongly flattened head with a very wide, upturned mouth and a brown, well-camouflaged body. As a typical ambush hunter it lies motionless and half-buried on the soft bottom and lures prey with a worm-like appendage near the mouth; when a small fish approaches it is engulfed in a flash. The fish is so sedentary that it barely moves when touched and can produce sounds out of water. The IUCN assesses the species as Least Concern (LC).
