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
Ökologie
seewasser bathydemersal; tiefenbereich ? - 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.
Length at first maturity / Size / Gewicht / Alter
Maturity: Lm 98.5, range 97 - 100 cm
Max length : 108 cm Männchen/unbestimmt; (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).
Life cycle and mating behavior
Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven
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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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): 4.3 ±0.3 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (67 of 100).
