Biología     Glosario (por ej. epibenthic)

A benthic species. Found on coastal to offshore on continental shelf in open sandy, muddy and silty habitat, including estuaries and intertidal zones. Mainly feeds on bony fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Maturity size 35-42 cm WD (males) and 44-46 cm WD (females); hatch size 22-25 cm DW. Produces litters of 1-6 pups (Ref. 114953). Caught by shrimp trawlers.

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). Distinct pairing with embrace (Ref. 205).
