Geographic Range [top]

Range Description:This species is distributed from the Indo-Malayan region throughout the tropical insular Pacific Ocean (Pyle 2001). It has been recorded from Sri Lanka (most likely a vagrant) in the west as far east as the Hawaiian Islands (USA), Marquesas Islands (French Polynesia) and Tuamotu Islands (French Polynesia), and from southern Japan in the north south to New South Wales (Australia) and Rapa (G.R. Allen pers. comm. 2006). It has been recorded at depths of 1-30 m. Range size ~10.3 million km2, from values estimated by Jones et al. (2002) based on projection of distribution maps from Allen et al. (1998).

Population [top]

Population:It is generally common (mean of 0.46 individuals per 200 m2 in northern Great Barrier Reef; Pratchett and Berumen 2008). There have not been any recorded changes in abundance, even in coral reef habitats with extensive coral loss (Berumen and Pratchett 2006). The global population is most likely stable.


Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Populations inhabit a wide variety of coral reef habitats, being frequently found in areas of rich coral growth in lagoons and on outer reefs. It occurs as solitary animals, in pairs or in small groups. The diet includes coral polyps, algae, sponges, fish eggs and benthic invertebrates (G.R. Allen pers. comm. 2006). This species lives exclusively within coral reef habitats, but has limited direct reliance on live corals (Pratchett 2005).

Use and Trade [top]

Use and Trade: This species is frequently exported through the aquarium trade (Pyle 2001). Approximately 5,000 individuals traded between 1988-2002 (Global Marine Aquarium Database 2009).

Threats [top]

Major Threat(s): This species is collected for the aquarium trade however there is no data on how this affects the population. There appear to be no other major threats to this species.

Conservation Actions [top]

Conservation Actions: There appear to be no species specific conservation measures in place (G.R. Allen pers. comm. 2006). In view of its wide range this species is likely to be present within many marine protected areas. Ongoing monitoring of catches by aquarium collectors is required.
