Females mostly yellow to yellowish-orange with a magenta band between the eyes and from the top of the eye to the dorsal-fin origin.

Distribution |
Occurs at Rowley Shoals, Western Australia, and on Flora Reef in the Coral Sea Marine Park, Australia. Elsewhere, the species is widespread in the Indo-West Pacific from Mauritius (Mascarenes), Indonesia east to Palau, north to southern Japan, south to Western Australia and the Coral Sea, and the Solomon Islands. Inhabits outer reef slopes in depths of 35-65 m, usually below 40 m. Forms small groups above patch reefs on sandy or rubble slopes. |
|
Features |
Dorsal fin X, 15-16; Anal fin III, 7; Pectoral fin 17; Lateral line scales 41-44; Gill rakers 8-11 + 22-24. Male with a fleshy protuberance on snout in front of upper lip; pelvic fins reaching just beyond anal-fin spines in male; caudal fin lunate with short filamentous tips in male. |

Biology |
A protogynous hermaphrodite. Forms small harems with a dominant male and a small group of females. If the male disappears, the highest-ranking female will change sex and colour over a couple of weeks to assume control of the harem. |
