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): 25.2 - 29.1, mean 28.1 °C (based on 1678 cells).
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00234 (0.00157 - 0.00350), b=3.02 (2.91 - 3.13), in cm total length, based on LWR estimates for this species (Ref.
93245).
Nível Trófico (Ref.
69278): 3.5 ±0.37 se; based on food items.
Resiliência (Ref.
120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec assumed to be <100).
Fishing Vulnerability (Ref.
