Taille / Poids / Âge
Ranges from the intertidal to offshore continental shelves down to 119 m (Ref. 9909). A carnivorous fish that feeds on large shellfishes (Ref. 58784). Ovoviviparous (Ref. 50449). Produces 6-10 pups a litter (Ref.114953). Biology little known (Ref. 9909). Utilized where it occurs but details lacking (Ref. 9909).
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
Preferred temperature (Ref. 123201): 25.2 - 29.1, mean 28.1 °C (based on 1678 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00234 (0.00159 - 0.00347), b=3.02 (2.91 - 3.13), in cm total length, based on LWR estimates for this species (Ref. 93245).
Niveau trophique (Ref. 69278): 3.5 ±0.37 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).
