Distribution

Temperate Australasia


Description

Two wide black bands across the body, the second band being light grey in some areas and becoming paler at night. Caudal fin reddish. Juveniles have a reddish tail, which darkens as the animals mature. The species is very common on reefs along the southern coast but is not often caught by line because it feeds on small invertebrates that are sucked off the bottom with a mouthful of sediment.


Information

Max Size: N/A cm

Sea Temperature Range: 11.9-22.1°C

Depth: 1-65 m

Habitat Generalization Index: N/A

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 (40.6% 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 (2 per transect)

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