Taxonomic Notes: For taxonomic treatment see Gomon (2006). Bodianus bilunulatus has long been confused with three other closely related species with which it is broadly sympatric: B. loxozonus, B. macrourus and B. perditio (Gomon 2006).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1

Little is known about population and life history characteristics. It is very widespread throughout the Indo-West Pacific and is fairly common in deeper areas. This species is moderately small and sought by aquarium fish collectors, but there is no catch data. It is probably occasionally caught by hook and line and spear fishing. This species is listed as Least Concern.

Geographic Range [top]

Range Description:This species is found in the Indo-Pacific from Somalia to Durban, South Africa to the Abrolhos Islands, Western Australia. In the Western Pacific, it is found from Wakayama, Japan to Bali, Indonesia and New Caledonia. It is evidently absent from the Red Sea, northwestern Indian Ocean and the east coast of Australia. The relatively poor representation of this species in collections, especially from Indonesia and southeast Asia, may be due to its occurrence on deep offshore reefs. This habitat is poorly collected at many localities (B. Russell pers. comm. 2008).
Countries occurrence:
Australia; British Indian Ocean Territory; Comoros; India; Indonesia; Japan; Kenya; Madagascar; Malaysia; Maldives; Mauritius; Mayotte; Micronesia, Federated States of ; Mozambique; New Caledonia; Palau; Philippines; Réunion; Seychelles; Somalia; South Africa; Sri Lanka; Taiwan, Province of China; Tanzania, United Republic of; Yemen

Population:There is no population information available for this species. This is fairly common in some areas and in deeper waters.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a large species, to about 310 mm SL. It occurs on deep reef slopes rich with invertebrates such as sponges and seawhips, but young adults are occasionally seen much shallower. Specimens have been taken at depths of 8-160 m. It is usually solitary in coral and rocky reefs. It feeds mainly on benthic, hard-shelled, invertebrates such as mollusks and crustaceans. It is protogynous (DeMartini et al. 2005). Size at sex change: 38.6-40.5 cm L.

Use and Trade [top]

Use and Trade: This species is collected for the aquarium trade. It is probably occasionally caught by hook and line or speared, and eaten.
