Etymology: Oxynotus: oxys (Gr.), sharp; notos (Gr.), back, referring to its keeled back (“dorso carenato”) (See ETYFish); bruniensis: -ensis, Latin suffix denoting place: the shore of Bruny Island, Tasmania, where holotype was discovered in a “dried … but fair state of preservation” (See ETYFish).

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи анального плавника: 0. Uniform grey-brown coloration; short, blunt snout; high sail-like dorsal fins with spines and broad apices, first dorsal spine inclined backward; high, thick triangular body with large, rough denticles; circular spiracles; lanceolate upper teeth, lower blade-like teeth in less than 12 rows (Ref. 247).
Body shape (shape guide): elongated.
Found on outer continental and insular shelves and uppermost slopes (Ref. 247). Probably feeds on bottom invertebrates and fishes. Ovoviviparous (Ref. 205). Taken incidentally with bottom trawls but probably not used (Ref. 247).
Ovoviviparous, with 7 young in a litter (Ref. 247). Size at birth about 24 cm (Ref. 6871). Distinct pairing with embrace (Ref. 205).
