Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 0. Broad diamond-shaped pectoral disc almost twice as wide as it is long; tail shorter than body with black and white bands and a small sting; tentacle at rear edge of each spiracle (Ref. 5578). Grey, green or brown above, often with darker mottling; white below; can change color of upper disc rapidly to match substrate (Ref. 5578).

Occurs off sandy beaches, muddy estuaries and offshore banks. Found singly or in large groups (Ref. 5578). Feeds on a variety of fishes, crabs and polychaete worms (Ref. 5578). Ovoviviparous (Ref. 50449). Ability to change markings and color to blend into environment (Ref. 3263). Caught by offshore trawlers (Ref. 5578). Caught by shore anglers, it is prized for its strong fight when hooked, often released (Ref. 5578).

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). Distinct pairing with embrace (Ref. 205). One year gestation; up to 10 young (Ref. 5578).

Estimates based on models

Preferred temperature (Ref. 123201): 14.5 - 27.1, mean 25.3 °C (based on 72 cells).

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

Bayesian length-weight: a=0.00776 (0.00351 - 0.01718), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.65 se; based on food items.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec=10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).

Catégorie de prix (Ref. 80766): Medium.
