Biologi     Ordlista (t.ex. epibenthic)

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 | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

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):  PD50 = 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).
Trofisk nivå (Ref. 69278):  4.3   ±0.3 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (67 of 100).
