Maturity: Lm ?, range 170 - ? cm
Max length : 240 cm WD hane/ej könsbestämd; (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 | Reproduktion | Spawnings | Egg(s) | Fecundities | 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).
