Distribution

Tropical Indo-Pacific


Description

Only known from the Coral triangle region and usually associated with branching Acropora corals. Sometimes has a dark marking on the upper surface of the tail base. Yellow pelvic fins on adults distinguish this from the most similar members of the genus. A. batunai and A. curacao both have white pelvic fins as adults and broader distributions, while A. leucogaster also has yellow fins, but also has a distinct black pectoral spot. Juveniles of this species and A. batunai are very difficult to distinguish.


Information

Max Size: 10 cm

Sea Temperature Range: 22.8-31.3°C

Habitat Generalization Index: 3.19

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Vulnerable

Occurrence: Common (30% of sites)

Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed

Abundance: Many (42 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
