Elasmobranchii (sharks and rays) > Squaliformes
(Bramble, sleeper and dogfish sharks) > Centrophoridae
Etymology: Centrophorus: Greek, kentron = sting + Greek, pherein = to carry (Ref. 45335).
Environment / Climate / Range
Marine; bathydemersal; depth range 760 - 770 m (Ref. 47737). Tropical
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 97 - 100 cm
Max length : 108 cm male/unsexed; (Ref. 58048)
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.
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
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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).

Phylogenetic diversity index (Ref. 82805
= 0.5003 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00288 (0.00130 - 0.00641), b=3.15 (2.95 - 3.35), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.4 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153
): High to very high vulnerability (71 of 100) .
