They are found in great abundance in shallow water on NSW reefs but decline rapidly in numbers towards the south. Juveniles are also occasionally found near the entrances of estuaries.
Information
Max Size: 30 cm
Sea Temperature Range: 13-25.2°C

Habitat Generalization Index: 44.96
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: Common (49.0% 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 (36 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
