NE of Forster, New South Wales, around southern Australia to off Ningaloo Reef, Western Australia, including Tasmania; also the Lord Howe Rise and Norfolk Ridge in the Tasman Sea, and off Macquarie Island and Heard & McDonald Islands in the Southern Ocean. Elsewhere the species in circumglobal in temperate and sub-Antarctic latitudes (except the North Pacific).
A common inhabitant of abyssal depths in the world's oceans.

Dorsal fin 5-7 + 48-55; Anal fin 36-49; Caudal fin 20; Pectoral fin 17-25; Pelvic fin 5-6; Lateral-line scales 120-137.
Body of moderate depth (16-18% SL), rather elongate, compressed; caudal peduncle very slender. Head moderately small (21-27% SL), circular in cross section; eyes of moderate size (24-28% HL); interobital of moderate breadth (94-96% eye diameter); mouth moderately large (upper jaw length 44-47% HL), nearly horizontal, tip of maxillary reaching to below posterior edge of eye; snout pointed, projecting well forward of jaws; teeth uniformly small, pointed, narrow band in each jaw; chin with tiny barbel (6-10% HL).  
Scales tiny, cycloid, covering head and body, extending well onto unpaired fins, 120-137 oblique rows intersecting lateral line; lateral line smoothly curved with flexure above pectoral fin. Anus immediately before anal fin. 
Two separate dorsal fins, first with short base and filamentous second fin ray; second fin very elongate of rather uniform height; anal fin with central rays noticeably shorter than those anteriorly and posteriorly separating fin into two lobes; caudal fin rounded. Pelvic fins arising midway between eye and pectoral fin base, reaching about half way to anus.

Etymology

The specific name is from the Latin rostrata (= beaked), in reference to the “peculiarly produced snout, which forms a short, triangular, pointed lamina, sharply keeled on the sides, and overreaching the cleft of the mouth”.
