Elasmobranchii (hajar och rockor) (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).
Taxonomic Remarks
Available evidence suggests that this species refers to the true C. granulosus from off
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).

Ekologi
marina djupbottenlevande; djupintervall 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).
