Size / Vikt / Age
Könsmognad: Lm ? range ? - ? cm
Max length : 75.0 cm TL hane/ej könsbestämd; (Ref. 26938)
Taggstrålar i ryggfenan (totalt) : 1. Rounded snout; head with seam-like sensory grooves on head; pectoral fins large; first dorsal fin with a long, sharp spine; a separate anal fin, not extending past the level of end of second dorsal fin. Curved club-shaped appendage between eyes in males. Lateral line canals in open grooves (Ref. 26938). Upper surface silvery gray, lower surface white (Ref. 6902).
Body shape (shape guide): elongated.
Solitary (Ref. 26340). Oviparous (Ref. 205). Eggs are encased in horny shells (Ref. 205). Unlikely to be seen by divers since this ratfish lives in very deep water (Ref. 26938).
