More Info
Distribution |
Rottnest Island, and offshore reefs of Western Australia, and Ashmore Reef in the Timor Sea, around the tropical north to at least Jervis Bay, New South Wales; also Christmas Island and Cocos (Keeling) Islands in the eastern Indian Ocean, and the Lord Howe Province and Norfolk Island in the Tasman Sea. Elsewhere the species is widespread in the tropical, Indo-Pacific. Inhabits sheltered inshore and lagoon reefs, often over sand/rubble areas. Juveniles prefer shallower lagoons, reef flats and patch reefs, usually around algal growth - and may enter silty inshore waters. |
Features |
Dorsal fin IX, 10; Anal fin III, 9; Pectoral fin 13-15; Median predorsal scales 6-8; Cheek scale rows 3: 1(6-7), 2(6-9), 3(3-5). Terminal phase males usually have 2 conical teeth on side of upper dental plate (absent in females), with lips mainly covering the plates. Caudal fin rounded in small females, with prolonged lobes in large adults. |
Feeding |
Feeds on feed on benthic turf algae and detritus scraped from dead corals. |
Biology |
Protogynous hermaphrodite. |
Fisheries |
Taken as bycatch in artisinal fisheries in many parts of its range. |
