Inhabits warm-temperate to tropical shallow bays and beaches (Ref. 2850). Feeds on crustaceans and small fishes (Ref. 37955). Ovoviviparous (Ref. 50449). Has a small venom apparatus which has limited use as a defense organ (Ref. 37955). Maximum length reported to reach 150 cm (Ref. 37955).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

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).

Estimates based on models

Preferred temperature (Ref. 123201): 17.7 - 28.8, mean 23.4 °C (based on 100 cells).

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

Bayesian length-weight: a=0.00776 (0.00352 - 0.01710), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.0 ±0.65 se; based on food items.

Resiliens (Ref. 120179): Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 21.4 [4.0, 100.8] mg/100g; Iron = 0.728 [0.188, 2.073] mg/100g; Protein = 22.7 [19.3, 25.6] %; Omega3 = 0.271 [0.078, 0.792] g/100g; Selenium = 20.3 [6.4, 60.1] μg/100g; VitaminA = 9.76 [3.37, 28.18] μg/100g; Zinc = 0.569 [0.277, 1.042] mg/100g (wet weight);
