Information

Max Size: 55 cm

Sea Temperature Range: 14.1-25.3°C

Depth: N/A

Habitat Generalization Index: 32.12

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: Frequent (13.3% 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: Many (17 per transect)

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