Description

The ocean jacket is a large filefish of the family Monacanthidae from the temperate waters around southern Australia. The species grows to about one metre and has an elongate, laterally compressed body with a long snout and the filefish-typical first dorsal fin in the form of a single erect spine. Adults live on the continental shelf and slope, while juveniles appear seasonally in schools in shallow coastal water. As an omnivore it feeds on a variety of invertebrates and plankton. The ocean jacket is an important commercial fish in Australia. It is harmless to humans.
