Description

The Lerma catfish is a North American catfish (Ictaluridae) from fresh water of the Lerma and Santiago systems in central Mexico. The species grows to about 30 cm and has a stocky, grey-brown body with long barbels, an adipose fin and a flattened head. As a nocturnal bottom-dweller it searches rivers and lakes for insect larvae, molluscs, crustaceans and small fish. The stout pectoral and dorsal spines can give a painful puncture wound when handled.
