Temperate Australasia


Description

Characteristic white patch at the back of the head, which contrasts with the dark body; this patch is present even during the colourful juvenile phase.

Males become very aggressive during the breeding season, when they usually develop additional light-coloured patches on the head.


Information

Max Size: 14 cm

Sea Temperature Range: 13-24.6°C

Habitat Generalization Index: 42.01

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 (46.8% 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: Several (7 per transect)

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