Distribution

Temperate Australasia


Description

Females and males differ distinctly in markings, both potentially confused with A. ornata, which has longer spines above the eyes and a more intricate pattern on the body. Females have a pattern of scribbled orange, black and white markings over the body, and the less common males have a distinctive arrangement of yellow, blue and white dots and stripes.


Information

Max Size: 20 cm

Sea Temperature Range: 10.1-23.3°C

Depth: 10 - 200 m

Habitat Generalization Index: 3.5

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 (21.4% 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: Solitary (1 per transect)

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