Temperate Australasia


Long thin fish with relatively short snout, pale belly, and prominent white-edged black spot on the tail. The species is not often seen, perhaps because it occurs in deeper water than most other rock whiting.


Max Size: 12 cm

Sea Temperature Range: 13-22.5°C

Depth: 5-25m

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: Least Concern

Occurrence: Infrequent (5.7% 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 (3 per transect)

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