Adult Cloud Wrasse have a boomerang-shaped pinkish mark on the cheek. The fish in the image is a juvenile in which the anterior part of the boomerang marking is indistinct but the descending posterior region is visible.
The Cloud Wrasse grows to 12 cm in length.
The Cloud Wrasse is classified in the family Labridae. It looks similar to several other species of Halichoeres (especially the Pink-belly Wrasse H. margaritaceus), but can usually be separated by cheek colouration.
It occurs widely in tropical marine waters and some temperate waters of the Indo-West Pacific. In Australia it occurs off north-western Western Australia and from the northern Great Barrier Reef to the central coast of New South Wales.
