Etymology: Rhynchobatus: Greek, rhingchos = snout + Greek, batis, -idos = a sting ray (Raja sp.) (Ref. 45335).

Benthic (Ref. 114953). Occurs in shallow coastal waters, more or less stationary. Ovoviviparous (Ref. 50449). Adults feed mainly on small bony fishes and invertebrates. Females have litters of 2-5 pups. Maturity size unknown but born at 79-85 cm TL (Ref. 114953).
Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
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).
