Short description Identification keys | Morphology | Morphometrics
Vertebrae: 106 - 115. This species is distinguished by the following characters: large (>1.5 m maximum total length); body moderately robust; head moderately long (20.6-24.9% TL, 3.9-4.9 times in total length) and very robust; snout relatively short, horizontal preorbital length 4.8-8.1% TL, moderately rounded in dorsal view; first dorsal fin low and long, its height 4.4-6.5% TL, its soft length 11.0-16.6% TL), inner margin very long which is more than length from insertion of exposed spine to fin insertion; second dorsal fin large, similar in heigfree rear tip varying from slightly elongate in small individuals with free rear tip extension 0.9-2.2% TL in individuals < 70.0 cm TL, to moderately elongate in adults, 1.9-4.1% TL; lateral trunk denticles elevated on low, broad pedicel with strongly tricuspidate crowns in juveniles < 70.0 cm TL; denticles of large individuals low, not on pedicels, crown tear-drop shaped with one long posterior cusp; upper teeth of juveniles < 50.0 cm TL are strongly oblique; upper teeth of individuals > 70.0 cm TL with erect to slightly oblique cusps; lower teeth of all sizes are much larger than upper teeth, strongly oblique, blade-like; total vertebral centra 106-115; teeth 30-37/27-32; body uniformly brownish (sometimes greyish to greyish brown), slightly paler ventrally (Ref. 94782).
Cross section: oval.
Cross section: oval.
A common deepwater dogfish of the outer continental shelves and upper slopes, commonest below 200 m (Ref. 247); usually benthic and epibenthic at depths from 50-1440 m with most records from 200-600 m (Compagno, pers. comm. 07/07). Solitary (Ref. 26340). Adults feed mainly on bony fishes such as hake, epigonids, lanternfish, herring, smelts, cods, rattails, squid and crustaceans (Ref. 247, IUCN workshop 07/07). Males mature at about 105-118 cm TL (Ref. 94782). Ovoviviparous (Ref. 50449). This species is fished in Eastern Atlantic by bottom trawls, long lines, fixed bottom nets, hook and line and pelagic trawls; caught and discarded, or utilised from by-catch fisheries (IUCN discussion 07/07). Marketed smoked and dried salted for human consumption; also processed into fishmeal and a source of liver oil for squalene (Ref. 247).
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Young are born from 30 to 42 cm or more (Ref. 247). Distinct pairing with embrace (Ref. 205).
