Disc rhomboid, pectoral fin apex rounded, snout broadly triangular and snout tip lightly pointed. Eye and spiracle length more than 2 times the preorbital snout length. A dense band of spindle-like denticles starting between the eyes and covering the mid-disc and all surfaces of tail. A long row of large thorns from the interbranchial area to sting insertion, with some marginal thorns less developed in frontal and distal part of the row. Tail relatively long, slightly longer than the disc. One sting present. No skin folds on tail. Pelvic fins small.

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. Distinct pairing with embrace.
