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).

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).

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).西北太平洋: 西沙 (Paracel) 島與外海的 Zujiang 河口，香港。 一個相似種與也許同一種出現外海的馬爾地夫，斯里蘭卡與菲律賓。

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).
