Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Elasmobranchii (sharks and rays) > Squaliformes (Sleeper and dogfish sharks) > Centrophoridae (Gulper sharks)
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).

Issue
Portugal and so must be considered a junior synonym of the latter species. The purported syntype BMNH 1867.7.23.2 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 Ecology

Marine; bathydemersal; depth range 300 - 1400 m (Ref. 247). Deep-water; 43°N - 38°S, 18°W - 124°E (Ref. 54312)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

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: L_m 116.0, range 88 - 144 cm
Max length : 160 cm TL male/unsexed; (Ref. 5578)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Anal spines: 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).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

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).

Estimates based on models

Preferred temperature (Ref. 115969): 5.3 - 12, mean 9 (based on 147 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00263 (0.00121 - 0.00572), b=3.18 (2.99 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±0.63 se; based on food items.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec=1).
