Taille / Poids / Âge

Maturity: L_m ? range ? - 32 cm
Max length : 32.0 cm WD mâle / non sexé; (Ref. 114953)

A poorly known species; attains at least 32 cm DW, mature at this size (Ref. 114953). Ovoviviparous (Ref. 50449).

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). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00468 (0.00195 - 0.01123), b=3.12 (2.92 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.7 ±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 (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
