Taille / Poids / Âge

Maturity: L_m ? range ? - ? cm
Max length : 30.0 cm TL mâle / non sexé; (Ref. 57911)

Deep water species on the continental slope. Feeds on worms, isopods and amphipods. The late-term embryos seem to gestate in a combined uterine/cloacal chamber. Produces up to 2 pups during each pregnancy. Maturity size of males at ca. 15 cm TL, females at 20 cm TL; birth size at ca. 10 cm TL. It is reported to be locally abundant as many individuals have been collected together in a single trawl (Ref. 114953).

Estimates based on models

Preferred temperature (Ref. 123201): 3.3 - 15.6, mean 6.9 °C (based on 37 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01175 (0.00476 - 0.02897), b=2.88 (2.66 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.46 se; based on food items.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec=1-2).

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).
