Temperate Australasia


Not commonly seen by divers in shallow depths, but occasionally shows up in Sydney and Jervis Bay in NSW, and in northern New Zealand. Black body patterning, upper head and snout profile and lack of extended rays on the soft (rear) dorsal fin distinguish it from the much more commonly seen long-snouted boarfish Pentaceropsis recurvirostris


Max Size: 100 cm

Sea Temperature Range: 11.4-22.6°C

Depth: N/A

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: Infrequent (2.3% 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.
