Max Size: 44 cm
Sea Temperature Range: 16-29.3°C
Habitat Generalization Index: 1.61
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: Least Concern
Occurrence: Infrequent (8.3% 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: Few (5 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
