Description

The Blackfin woodcat is a driftwood catfish (Auchenipteridae) from fresh water of the Parana and La Plata basins in South America. The species grows to about 20 cm and has an elongate, grey-brown body with a flat head, barbels and an adipose fin. As a nocturnal bottom-dweller it shelters by day in cavities and under wood and hunts insects, small fish and invertebrates by night; fertilisation is internal. The stout, sharp dorsal and pectoral spines can give a puncture wound when handled.
