Benthic and more or less stationary in inshore coastal waters. Feeds on fish and shrimps (Ref. 28587). Ovoviviparous. Females have litters of 2-3 pups. Males mature at ca. 46 cm TL, females at ca. 52 cm TL; birth size at ca. 15 cm TL (Ref. 114953).

Life cycle and mating behavior Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

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. 115969): 24.8 - 28, mean 27.3 (based on 205 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00295 (0.00151 - 0.00578), b=3.13 (2.96 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 4.1 ±0.71 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. 59153): Moderate to high vulnerability (50 of 100).

Categoria de preço (Ref. 80766): Low.
