Least Concern in view of its wide range, abundance and no major threats. This species has exhibited localized declines in abundance at Moorea (French Polynesia), but it is unclear whether this is linked to coral loss.
|Range Description:||This species is distributed throughout most of the Indo-Pacific region. It has been recorded from the East African coast in the west to Polynesia, including the Hawaiian Islands (USA), Marquesas Islands (French Polynesia) and Ducie Island (Pitcairn Islands, UK) in the east. The range extends from southern Japan in the north to Lord Howe Island (Australia) and Rapa Iti (Austral Islands, French Polynesia) in the south. Vagrants are occasionally seen in the eastern Pacific at the Galapagos Islands (Ecuador) and Cocos Island (Costa Rica). The species is very widespread with an approximate range size of ~81 million km2, from values estimated by Jones et al. (2002) based on projections of distribution maps from Allen et al. (1998). It is found at depths of 1-60 m.|

|Population:||It is a common species often with stable populations (G.R. Allen pers. comm. 2006).|
|Habitat and Ecology:||This species is found in lagoons and on outer reefs where it is most commonly observed in rocky areas, either slopes or in the inter-tidal zone (especially juveniles). Animals occur singly, paired, or in small aggregations. Favoured food items include nudibranchs, tubeworm tentacles, coral polyps and algae (G.R. Allen pers. comm. 2006). It rarely feeds on live corals (Pratchett 2005), but has exhibited a decline in abundance from 1979 to 2003 at Moorea (Berumen and Pratchett 2006).|
|Major Threat(s):||There appear to be no major threats to this species.|
|Conservation Actions:||There appear to be no species-specific conservation measures in place. This species occurs in marine protected areas.|
