Short description Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0; Anal soft rays: 0. Rostral ridges widely separated over their entire length; anterior nasal lobe reaching to level of inner corner of nostril, posterior nasal flap wide; spiracle with two moderately developed folds, the outer one more prominent; thorns relatively small, present around inner margin of orbits, between spiracles, on shoulders, and along midline of disc and tail; Upper surface khaki-brown, underside white (Ref. 6675).

Inhabits sandy and muddy bottoms, from the intertidal zone to about 100 m. Sometimes near rocky reefs (Ref. 12951). Slow swimming over bottom or partially buried. Feeds on benthic invertebrates and fishes. Ovoviviparous, one or two litters per year with 4-10 embryos.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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). One or two litters per year, of 4-10 embryos (Ref. 6675)
