Biologie     Glossaire (ex. epibenthic)

Rare species found offshore (Ref. 5578). Ovoviviparous (Ref. 50449). Probably caught by trawlers (Ref. 5578).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 12.3 - 24.2, mean 15.9 °C (based on 26 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00295 (0.00151 - 0.00578), b=3.13 (2.96 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (52 of 100).
