The Crested Morwong can be recognised by the dark stripe, which crosses from the spiny part of the dorsal fin to the lower lobe of the caudal fin. There are pairs of knob-like protrusions in front of the eyes and above the upper lip. The dorsal fin is tall anteriorly, then decreases in height over the next four spines, with the rest of the fin being long-based and low.
The Crested Morwong grows to about 35 cm in length.
It occurs in tropical and warm temperate waters of the Western Pacific.
In Australia it is known from southern Queensland to the central coast of New South Wales. It is usually seen on shallow, sheltered coastal and estuarine reefs.
