The saddle wrasse occurs only around the Hawaiian Islands in the central Pacific, where it is one of the most common reef fishes. The species grows to about 28 cm and has a blue-green body with a conspicuous orange to red band behind the head, the 'saddle'. Like many wrasses it is a protogynous hermaphrodite: fish begin life as females and can later change into males. It feeds on small invertebrates on the reef. The IUCN assesses it as Least Concern (LC).
