Elasmobranchii (sharks and rays) > Squaliformes (Sleeper and dogfish sharks) > Oxynotidae (Rough sharks)
Etymology: Oxynotus: oxys (Gr.), sharp; notos (Gr.), back, referring to its keeled back (“dorso carenato”) (See ETYFish); centrina: From “Centrina,” name for this shark dating to at least Giovio’s De romanis piscibus (1524), presumably derived from centrum (L.), prickle or sharp point, referring to spines on both dorsal fins (See ETYFish).
More on author: Linnaeus.

Environment: milieu / climate zone / depth range / distribution range Ecology
Marine; bathydemersal; depth range 60 - 1309 m (Ref. 128029). Deep-water; 70°N - 17°S, 25°W - 36°E (Ref. 54693)
Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri
Eastern Atlantic: Bay of Biscay and Mediterranean Sea to Senegal, north to Cornwall, England (apparently as a stray). Compagno et al. (Ref. 5578) reports this species as ranging south to Cape Point, South Africa but Springer 1990 (Ref. 10718) notes Bass et al. 1976 as considering specimens from Walvis Bay distinct from Oxynotus centrina calling attention to the considerably greater distance between dorsal fins in Mediterranean specimens than in specimens taken south of the equator.

Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Anal spines: 0. A small bizarre-looking shark with an unmistakable high body and bristly textured skin (Ref. 5578). Uniformly grey to grey-brown (Ref. 5578).
Found on the outer continental shelf and upper slope (Ref. 5578). Depth range from 60-660 m (Ref. 247) and from 549-777 m in the eastern Ionian Sea (Ref. 56504), and 818-1309 m NW Africa (Ref. 128029). Feeds on polychaetes (Ref. 247) and sipunculids (apparenly a suction feeder which mainly feeds on worm-like prey), which are rapidly digested, and the rapid gastric evacuation could partially explain the vacuity of several guts; teleosts, crustaceans and echinoderms are considered as accessory prey items, thus recorded predation on egg cases of the smallspotted catshark Scyliorhinus canicula remains an occasional phenomenon (Ref. 81816). Ovoviviparous (Ref. 205). Utilized for fishmeal, oil, and smoked and dried salted for human consumption (Ref. 247).
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Ovoviviparous, without a placenta, with about 7 or 8 young in a litter (Ref. 247). Distinct pairing with embrace (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 123201): 9.5 - 15.3, mean 13.3 °C (based on 283 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00163 - 0.00849), b=3.15 (2.94 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.1 ±0.3 se; based on diet studies.
Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec=7).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
Climate Vulnerability (Ref. 125649): Moderate vulnerability (38 of 100).
