Elasmobranchii (sharks and rays) > Squaliformes
(Sleeper and dogfish sharks) > Centrophoridae
Etymology: Centrophorus: centr[um] (L.), prickle or sharp point; phorus, from phoreus (Gr.), bearer or carrier, referring to grooved spines on dorsal fins. (See ETYFish); lusitanicus: -icus, belonging to: Lusitania, ancient name of Portugal, type locality (although identity of holotype is in dispute, treated as a junior synonym of C. granulosus by some workers). (See ETYFish).
Portugal and so must be considered a junior synonym of the latter species. The purported syntype BMNH 18126.96.36.199 is not a type specimen and refers to a separate long-finned species (see Ref. 116740 for available evidence).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 300 - 1400 m (Ref. 247). Deep-water; 43°N - 38°S, 18°W - 124°E (Ref. 54312)
Eastern Atlantic: Portugal, Senegal, Côte d'Ivoire to Nigeria. Western Indian Ocean: southern Mozambique and possibly Natal, South Africa (Ref. 11228). Western Pacific: China (Ref. 6577) and Taiwan (Ref. 247); occurrence in the Western Central Pacific uncertain but should be watched for (Ref. 31367). Often confused with Centrophorus niaukang and Centrophorus granulosus (Ref. 31367).
Length at first maturity / Size / Weight / Age
Maturity: Lm 116.0, range 88 - 144 cm
Max length : 160 cm TL male/unsexed; (Ref. 5578)
soft rays: 0. A large, stout gulper shark with a broad snout, a long, low 1st dorsal fin and a high 2nd dorsal fin; pectoral rear tips moderately long; denticles low, flat and smooth (Ref. 5578). Pearl-grey in color (Ref. 5578).
A large deepwater dogfish of the outer continental shelves and upper slopes (Ref. 247). Feeds on bony fish, small dogfish sharks, squids, and lobsters (Ref. 247). Ovoviviparous (Ref. 50449). Utilized as food fish and as fishmeal (Ref. 247).
Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Number of young 1 to 6 per litter; size at birth 33-36 cm TL (Ref. 247, Ref. 58048). Distinct pairing with embrace (Ref. 205).
