The eel-tailed catfish is a freshwater fish with a large head, thick lips and a tail that narrows like an eel's. It lives in the Murray-Darling river system in eastern Australia. Its fins carry sharp, venomous spines, so it is important to know it when you are in the water.1

Fatgs

Males and females both help: the parents guard the nest of eggs until they hatch.1

The nest is built one or two weeks before spawning, when water reaches 20–24 °C.1

Juveniles often gather in groups, although adults usually live alone.1

Its populations in the southern Murray-Darling have declined so much that most are extinct or nearly so.1
