Short description Morfología | Morfometría

Disk broad with long sharply pointed wings and projecting snout. Tail very long, Few middorsal spines on disk in adults (Ref. 7251). Greyish, reddish chocolate or dusky brown above. Lower surface either pure white or whitish. Teeth green (Ref. 6902).

Biología     Glosario (por ej. epibenthic)

Found frequently in coastal waters to 10 m depth, mainly in shallow estuaries. Capable of traveling long distances, occasionally leaps out of the water. Swims in midwater. Cruises slowly over the bottom, rooting out bivalves with its beak and wings when feeding (Ref. 7251). Ovoviviparous (Ref. 50449).

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).
