Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
Generally found in lagoons and outer reefs where coral growth is prolific (Steene 1978, Pyle 2001, G.R. Allen pers. comm. 2006). Juveniles most often seen in shallower water among branching corals belonging to the genus Acropora. Individuals have very large home ranges. While detailed feeding observations have not been completed, this species is an obligate corallivore.

Justification
Chaetodon bennetti feeds exclusively on live coral, making it susceptible to extensive coral loss. This species is naturally low in abundance and therefore it cannot be reliably surveyed using normal sampling protocols, so it is unknown whether there have been significant declines in abundance at sites where there has been extensive coral depletion. It is possible that slight declines in abundance will make local populations no longer viable. It is listed as Data Deficient. Research is recommended on the ecology and natural history of the species. Monitoring of populations is also required.

Population

Population

This is an uncommon species, occurring in low abundance throughout its range (e.g., mean of 0.03 individuals per 200 m2 in Moorea, French Polynesia; Berumen and Pratchett 2006). This species is likely to decline in abundance following coral loss, but it is too rare to reliably sample using standard survey techniques. However, it is widespread and the global population is potentially large. It is usually observed as solitary individuals, but sometimes in pairs (G.R. Allen pers. comm. 2006).

Threats

Major Threats

This species relies on live coral for food and/or recruitment, and may therefore decline in abundance following climate-induced coral depletion (Pratchett et al. 2008). Currently, there have been no documented declines associated with coral loss, and there appear to be no other major threats to this species.

Management

Conservation Actions

Conservation Actions

There appear to be no species-specific conservation measures in place. This species is present within marine protected areas. Monitoring of this species is needed in conjunction with coral monitoring, though it will require specific sampling methods to reliably estimate its abundance. Research is required to establish its specific dietary requirements and reliance on coral.

Bluelashed butterflyfish

The bluelashed butterflyfish, Chaetodon bennetti, is a species of butterflyfish (family Chaetodontidae). It is found in the Indo-Pacific from East Africa to the Pitcairn Islands, north to Japan and south to Lord Howe Island and Rapa Iti.[1]

It grows to a maximum of 20 cm (almost 8 in) long. The body is yellow with a black patch surrounded by a blue circle below the dorsal fin and two curved blue lines above the belly. Its vertical black eyestripe is flanked by two blue lines.[1]

Like the other butterflyfishes with angular yellow bodíes with black eyestripes and (except in the present species) a single differently-colored patch, it belongs in the subgenus Tetrachaetodon. Among this group it seems to be the most basal living species. If Chaetodon is split up, this subgenus would be placed in Megaprotodon.[2]

The bluelashed butterflyfish is found in seaward and lagoon reefs in areas with rich coral growth. Juveniles may be found in shallow Acropora thickets. Adults occur in pairs. This species feeds largely on coral polyps.[1]
