Description

The dusky morwong is a large reef fish of the morwong family (Cheilodactylidae) from the temperate waters around southern Australia. The species grows to about 1.2 metres and has an elongate, greyish body with a small head and thick lips. It inhabits seagrass beds and the vicinity of rocky outcrops in shallow to moderately deep coastal water. With its fleshy lips it searches the bottom for polychaete worms, isopods, amphipods and other small invertebrates, which it sucks up with the sand and sifts. The dusky morwong is a slow, site-attached reef dweller and is harmless to humans.
