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); isodon: iso-, from isos (Gr.), equal; odon (Gr.), tooth, referring to similarly-shaped teeth on both jaws. (See ETYFish).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marinhas batidemersal; intervalo de profundidade ? - 770 m (Ref. 47737). Tropical
Northwest Pacific: Xisha (Paracel) Islands and off the Zujiang River mouth, Hong Kong. A similar and perhaps identical species occurs off Maldives, Sri Lanka, and the Philippines.
Comprimento de primeira maturação / Tamanho / Peso / Idade
Maturity: Lm 98.5, range 97 - 100 cm
Max length : 108 cm macho/indeterminado; (Ref. 58048)
Ovoviviparous (Ref. 50449). Diet poorly known, but stomachs examined contained fishes and cephalopods. Caught by demersal fisheries operating in deepwater areas. Utilized for its meat, fins (low value) and liver oil (very high value)(Ref.58048).

Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205). Gives birth to litters of 2 pups after an unknown gestation period; no apparent reproductive synchronicity. Largest embryo recorded was 32 cm TL (Ref.58048).
