|Scientific Name:||Chaetodon semilarvatus|
|Species Authority:||Cuvier, 1831|
Chaetodon melanopoma Playfair, 1867
|Red List Category & Criteria:||Least Concern ver 3.1|

While there have been no declines documented, this species feeds predominantly on live coral, which may make it susceptible to extensive coral loss. However, it has a relatively wide distribution, apparently large population and no obvious major threats other than coral loss. It is listed as Least Concern.
|Range Description:||This species is endemic to the Red Sea and Gulf of Aden, northeast to the southern coast of Oman (Allen 1980, G.R. Allen pers. comm. 2006). It has been recorded at depths of 1-20 m.|
Native:Djibouti; Egypt; Eritrea; Israel; Jordan; Saudi Arabia; Somalia; Sudan; Yemen
|FAO Marine Fishing Areas:||
Indian Ocean – western

|Population:||It is generally common with stable populations (G.R. Allen pers. comm. 2006). There is no evidence to suggest any declines.|
|Habitat and Ecology:||This species is associated with areas of rich coral growth in relatively shallow water (G.R. Allen pers. comm. 2006). It usually occurs in pairs or as larger aggregations of up to about 20 animals. Generally rests beneath Acropora plate corals during the day becoming active in late afternoon. This species is an obligate corallivore.|
|Major Threat(s):||This species generally feeds on live coral, and may therefore decline in abundance following climate-induced coral depletion (Pratchett et al. 2008). Currently there has been no documented declines associated with coral loss, and there appear to be no other major threats to this species.|
|Conservation Actions:||There appear to be no species-specific conservation measures in place. This species is believed to be present within marine protected areas. Monitoring of this species is needed in conjunction with coral monitoring, as well as determination of the degree of co-dependence between this species and corals.|
