The Old Wife is easily recognised by its distinctive shape and colouration. It has a deep body, and two separate dorsal fins, the second being sickle-like.

The body is silver-white to brown and has six to eight black bands of variable width.

Juveniles are more elongate than adults and have a blotched colour pattern and a white-rimmed spot on the soft dorsal fin.

The dorsal fin spines of the Old Wife contain a venom which can cause severe pain.

Adults are common on coastal reefs, often seen as solitary individuals or in pairs, but will also form large schools. Juveniles live in estuaries.

This species grows to 25 cm.

The Old Wife was given its rather derogatory name in reference to the sound it makes by grinding its teeth after it is caught.

Enoplosus armatus is the only species in the family Enoplosidae.

The Old Wife is endemic to Australia. It is found in southern waters from southern Queensland to south-western Western Australia.
