Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
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). Distinct pairing with embrace (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00366 - 0.01891), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.37 se; based on food items.
Resilienza (Ref.
120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Assuming Fec<10).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
