Description
Size: 12-31 cm disc width

Color: Brown- or light brown-colored disc, with many brighter spots all over the body.

It is a cartilaginous fish with a quite narrow disc. The mouth is situated on the underside of the flabby body and small, bulging eyes are situated on top of the head, surrounded by small spiracles. Spiracles are tiny holes that allow the ray to breathe when resting on the ocean bottom, as in this position the mouth is covered. The stout tail is substantially shorter than the length of the body disc and bears a well developed fin at its tip. It has two dorsal fins, small and rounded, close to their pelivc fins. Dorsal spines (total): 0; Anal spines: 0; Vertebrae: 98-102.

Dioecious, internal (oviduct) fertilization, internal live bearers. 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 specialized structures.
