Amblyglyphidodon batunai
Batuna Damsel
Distribution
Description
Dark, large scale edges above the lateral line, becoming fainter towards the lower rear portion of the body. Often has purple or blue-green spots on the face and breast, and sometimes may have a dark marking on the upper surface of the tail base. Very similar to A. ternatensis, but has longer, white pelvic fins (in adults). Juveniles may be yellow and look almost identical to A. ternatensis. The latter species is not known from Australia.
Information

Conservation and Rarity
IUCN Status: Vulnerable
Occurrence: Infrequent (9.6% 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 (49 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
