Short description Morfología | Morfometría

Narrow white marginal band around disk; white spot anterior to spiracle and posterior to eye; ventral surface plain; spiral valve with 11-14 turns (Ref. 12693).

Wounds caused by the dorsal spines are extremely painful and can be fatal. Sold fresh for human consumption (Ref. 32457). Total length maybe greater than 200 cm.

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