板鳃亚纲 (鲨鱼与 鱼) (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); 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
生态学
海洋 深海底的; 深度上下限 ? - 770 m (Ref. 47737).
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 / 大小 / 重量 / 年龄
Maturity: Lm 98.5, range 97 - 100 cm
Max length : 108 cm 雄鱼/尚未辨别雌雄; (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 | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
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).
营养阶层 (Ref.
69278): 4.3 ±0.3 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 低的, 最小族群倍增时间4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (67 of 100).
