Description

The freshwater cobbler is an eel-tailed catfish from fresh water of southwestern Australia. The species grows to about 50 cm and has an elongate body tapering backward into an eel-like, continuous fin margin, with barbels around the mouth. On the dorsal and pectoral fins it bears strong, venom-linked spines that can deliver an intense, painful sting. As a nocturnal bottom-dweller it builds a nest of pebbles and guards the eggs. It hunts crustaceans, molluscs and insect larvae. The IUCN assesses the species as Least Concern (LC).
