This species is distinguished from its congeners by the following set of characters: snout elongated, narrow and depressed up to 56% BDL; trunk long, slender; vomerine tooth plate beak-like; eye largelength 8-12% BDL and height 5-7% BDL; long dorsal spine reaching slightly beyond apex of the dorsal fin; pelvic claspers slender rod-likel; deciduous skin; uniform chocolate brown when skin intact (Ref. 132499).
Cross section: oval.
Widespread on the continental slope and over seamounts and ridges. In terms of length measurements of specimens examined: largest female 44.5 cm BDL (107.5 cm TL), male 33.4 cm BDL (95.7 cm TL); smallest mature male 30.0 cm BDL (79.1 cm TL), largest adolescent male 24.9 cm BDL (67.2 cm TL); smallest mature female 36.2 cm BDL (85.9 cm TL), largest adolescent female 36.6 cm BDL (95.1 cm TL). Maturity was estimated at 28.6 cm BDL for males and 37.2 cm BDL for females (Ref. 132499).
