Description synthétique Clés d'identification | Morphologie | Morphométrie

A plain eagleray with a short, rounded snout; disc with broadly angular corners, and upper or lower jaw usually with 7 rows of plate-like teeth (Ref. 5578). Brown or blackish dorsally, white ventrally (Ref. 5578). No caudal fin (Ref. 5578).

Found in shallow lagoons (Ref. 3965), bays and estuaries; also offshore down to at least 95 m (Ref. 5578). Often found in groups (Ref. 5578). Feeds on benthic crustaceans, mollusks and fish. Ovoviviparous (Ref. 50449). Gestation period of 6-8 months, the females give birth to 3-7 young (Ref. 35388). Caught by shore and ski-boat anglers, usually released after capture (Ref. 5578). Flesh is highly esteemed (Ref. 3965).

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. 115969): 11.7 - 19.8, mean 15.2 (based on 318 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00123 - 0.01235), b=3.08 (2.82 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.6 ±0.54 se; based on food items.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec=3).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (83 of 100).

Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (47 of 100).

Catégorie de prix (Ref. 80766): High.
