Temperate Australasia


Rounded body with a distinctive fawn patch encircled by a large black ring around the base of the pectoral fin. The western animals have a less rounded body than southern animals and fine blue spots on the back, so two species are probably involved.


Max Size: 25 cm

Sea Temperature Range: 11-23°C

Depth: 4-146 m

Habitat Generalization Index: N/A

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: Not Evaluated

Occurrence: Infrequent (7.2% 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: Solitary (1 per transect)

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