marin benthopélagique; profondeur 1 - 110 m (Ref. 9862). Tropical; 28°N - 24°S, 32°E - 155°E

Length at first maturity / Taille / Poids / Âge
Maturity: Lm ?, range 170 - ? cm
Max length : 240 cm WD mâle / non sexé; (Ref. 58048)
Found in muddy bays and banks and on coral reefs from close inshore to 110 m depth (Ref. 9862). Ovoviviparous (Ref. 50449). Caught in bottom trawls, gillnets, seines, and fish traps (Ref. 9862, Ref.58048). Utilized for its meat and cartilage (possibly used as "filler" in shark fin soups as with other large eagle rays) (Ref.58048).
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.
123201): 24.9 - 29.1, mean 28.1 °C (based on 2154 cells).
Phylogenetic diversity index (Ref.

50 = 0.5078 [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.

Niveau trophique (Ref.
69278): 3.8 ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).
Fishing Vulnerability (Ref.
