Benthic (Ref. 114953). Occurs in shallow coastal waters, more or less stationary. Ovoviviparous (Ref. 50449). Adults feed mainly on small bony fishes and invertebrates. Females have litters of 2-5 pups. Maturity size unknown but born at 79-85 cm TL (Ref. 114953).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | 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): 23.2 - 28, mean 26.5 °C (based on 100 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5049 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00166 - 0.00830), b=3.11 (2.91 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.5 ±0.80 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

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

Catégorie de prix (Ref. 80766): Medium.
