Information

Max Size: 16 cm

Sea Temperature Range: 14.7-25.2°C

Depth: 1-40m

Habitat Generalization Index: 26.99

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 (30.2% 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: Large aggregations (106 per transect)

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