More Info


Off Newcastle, New South Wales, to south-west of Shark Bay, Western Australia including Tasmania; also south of Lord Howe Island, Lord Howe Rise and Wanganella Bank, Tasman Sea. Elsewhere the species occurs in New Zealand. Benthopelagic on the continental slope at depths between 450-1100 m, mostly between 600-900 m.


Dorsal fin II, 8-10; Pectoral fin 16-19; Pelvic fin 7; Gill rakers 6-9; Pyoric caecae 7-9.
Body shallow, somewhat cylindrical, head relatively large, head ridges sharp, narrow, dorsal profile concave; snout long, slender, sharply pointed, anterolateral margin completely supported by bone, area dorsally behind leading edge translucent, naked to sparsely scaled; underside of head naked anteriorly, with some scale patches above and behind mouth; nasla fossa naked; eye moderately large, much shorter than snout, mouth small, jaw teeth small, in three or four irregular series, outermost larger. 

Second dorsal-fin rays relatively well developed, similar in length to opposing anal-fin rays. 

Body scales moderate, somewhat deciduous, with almost parallel rows of short, slender spinules size and sub-ovoid with spinules arranged in sub-parallel series from 4 to 14 (varying in number with position of scale and size of specimen). 

Anus before anal-fin origin by 2-3 scale rows; light organ small, not visible externally, relatively short, extending from anus to midline between pelvic-fin bases; a narrow, scaleless, blackish streak extends from anus to base of ventral fins.


Reaches a total length of 35 cm.


Body overall uniform pale gray, with no distinctive markings; anterior portion of head translucent, mouth and gill cavity dark, orbit with black margin, lips and barbel pale; second ray of first dorsal fin black, otherwise dusky.
