More Info


Distribution

Occurs at Rowley Shoals, Western Australia, and in the Coral Sea. 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 near the bottom, above patch reefs on sandy or rubble slopes.

Features

Meristic 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

Form 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.
