Eastern Atlantic: France to South Africa, including the Mediterranean (Ref. 31367). Western Central Atlantic: northern Gulf of Mexico (Ref. 247, 6871). Indian Ocean: Mozambique, South Africa and the Aldabra Islands (Ref. 31367); Western Australia (Ref. 6871). Western Pacific: Japan, Papua New Guinea, and Australia (Ref. 31367).

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). Feeds mainly on bony fishes such as hake, epigonids, lanternfish, herring, smelts, cods, rattails, squid and crustaceans (Ref. 247, IUCN workshop 07/07). Ovoviviparous (Ref. 50449). Marketed smoked and dried salted for human consumption; also processed into fishmeal and a source of liver oil for squalene (Ref. 247). Number of litter recorded, one in Mediterranean females, and possibly 1 or 2 for the species. Males still immature at 45-58 cm, fully at 80-94 cm, suggesting maturity at 60-80 cm DW; females immature at 42-96 cm 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).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00235 (-0.10994 - 0.11464), b=3.17 (3.09 - 3.25), based on LWR estimates for species & family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 4.1 ±0.7 se; Based on diet studies.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Vulnerability (Ref. 59153): Very high vulnerability (87 of 100) .

Price category (Ref. 80766): High.
