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
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00659 - 0.03318), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.8 ±0.7 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.
