More Info


Distribution

East of Kiama, New South Wales, to south of Robe, South Australia, also southeast of Middleton Reef, Tasman Sea. The identity of specimens from New South Wales is uncertain and additional specimens are required to more accurately determine distribution. Elsewhere the species occurs in the  temperate, south-east Pacific: New Zealand and the Juan Fernández Islands, Chile. The species is bathydemersal on the continental slope at depths between 1425 - 2515 m.

Features

Dorsal fin II, 7-8; Pectoral fin 17-19; Pelvic fin 9-10; Gill rakers 8-10 (inner, 11-12); Pyloric caecae 8-10.
Head and snout moderate; head without modified scales forming stout ridges; a few small, deciduous scales on suborbital and lower jaw; snout naked ventrally and along anterior part of dorsal surface. Upper jaw teeth in 2 series, lower jaw teeth in a single row; chin barbel short, thin. Outer gill rakers of first arch short, flap like. 


Body scales deciduous, spinules exposed field reduced or lacking. 


Leading edge of long spinous ray of first dorsal fin with numerous short, reclined spinules; outer pelvic-fin ray slightly elongate.

Size

Reaches a total length of at least 16 cm.

Colour

In preservative - overall dark brownish, somewhat darker on head; blackish over operculum, gill membranes and jaws; fins dark.
