The Variegated Wrasse can be recognised by its colouration, which varies as the fish grows.
Juveniles are olive-green above and white below. They have bright orange spots on the head and belly. There is a dark brown stripe from the mouth to the eye. A series of narrow white bars extend from the dorsal fin onto the top of the body and there are three black ocelli on the front, middle and rear of the dorsal fin.
Female Variegated Wrasse have a grey-greenish body and irregular blackish bars on the back. There are irregular pink bars on the face, a vertical elongate black spot behind the eye and a black bar on the pectoral fin base. They also have three black ocelli on the dorsal fin.
Males are similar to the females, but have a greener body and may lose some of the ocelli in the dorsal fin.
The species grows to 17 cm in length.
The Variegated Wrasse occurs in tropical marine waters of the Indo-Pacific, from the Maldives, north to Japan, throughout Micronesia, south to Australia and east to Tonga.
In Australia the species is known from the north-western coast of Western Australia and from the northern Great Barrier Reef, Queensland to the northern coast of New South Wales.
