Descrição breve Chaves de identificação | Morfologia | Morfometria
Tail short armed with spine. Disk very broad. Very low dorsal and ventral finfolds on tail (Ref. 7251). Disk dark brown to grayish, lower surface of disc and of pelvic fins white, brownish, rosy or rusty cast. Tail white or rosy white below (Ref. 6902).
Maximum length measured is 140 cm (Ref. 5377). Occurs over sand and mud. Feeds on fishes, crustaceans, mollusks and plankton. Ovoviviparous, gestation lasting about 6 months with 4 to 7 embryos produced per female (Ref. 6676).
Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
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).
