Description

The Thicklip suckermouth catfish is a suckermouth catfish (Mochokidae) from fast-flowing, clear fresh water of the Congo basin in Central Africa. The species grows to about 15 cm and has a flattened body with a large, sucking lower lip with which it clings to rocks in strong current and rasps off algae, with fringed barbels. As a bottom-dweller it lives in oxygen-rich mountain rivers. The stout pectoral and dorsal spines can give a painful puncture wound when handled.
