Short description

Dorsal spines (total): 1; Anal spines: 0; Anal soft rays: 0. A longnose chimaera with a rather long, narrow, depressed snout, a small eye situated above or behind the mouth, a rather long first dorsal fin and spine, knobby tooth plates, and caudal fin lanceolate with no tubercles on upper edge but with a long terminal filament (Ref. 5578, 6871, 41248). Dark brown or blackish in color (Ref. 5578). No separate anal fin. Claspers are rod like, rather slender, unbranched, with tip somewhat swollen. Jugular and oral canals arising separately from orbital, with a short interspace; angular (maxillary) canal joining suborbital about 2/7 of distance from front level of eye toward tip of snout (Ref. 41248).

Found on the continental slope and ocean floor (Ref. 26346). Appears to feed mainly on shellfish and crustaceans (Ref. 6871). Maximum length 120 cm without tail filament (Ref. 26346).
