Known from various oceanic locations of the Pacific plate, ranging from the Hawaiian Islands to Palau and south to Samoa and the Marquesas Islands. Adults occur in small groups in shallow boulder regions, whilst juveniles are seen singly in rich coral habitats. Large adults have numerous fine pale-greenish lines over the head and along the body, but appear almost black at a distance, and are known as Black Surgeon in Hawaii. Small juveniles differ markedly in having bright colours and chevron-line markings. Grows large, length to 24 cm
