Rayons mous dorsaux (Total) : 75 - 83; Rayons mous anaux: 55 - 66; Vertèbres: 74 - 79. This species is distinguished by the following characters: when preserved, distinct, dark brown pigmentation dorsally between head and dorsal fin and on the sides of the light brown body; fresh specimens when newly caught with dark blue-like pigmentation on the peritoneum and body faintly reddish; D 75-83, A 55-66; vertebrae 74-79; vomer with up to four fangs, dentary with up to five fangs; penis length up to 10% SL, proximally covered by a large dorsal clasper and a smaller ventral clasper protected ventrally by a well-developed fleshy hood; eyes not externally visible in specimens longer than about 14.0 cm SL, while eyes of smaller specimens appear as a narrow, dark ring surrounding lighter tissue (Ref. 128809).
Rare species (Ref. 34024). Viviparous. Relatively often caught by commercial trawlers for it also occurs on the upper continental slope (Ref. 128809).
