Description

The Kessler's sea catfish is a sea catfish (Ariidae) from coastal and estuarine water of the eastern Pacific, from Mexico to Peru. The species grows to about 35 cm and has a stocky, grey-brown body with barbels at the mouth and an adipose fin; the male broods the eggs in his mouth. As a bottom-dweller it searches turbid water for crustaceans, molluscs and small fish. The stout, serrated dorsal and pectoral spines are venomous and can give a painful puncture wound.
