Short description Morfología | Morfometría

Obtuse snout, broader heart shaped disc. Olive to brownish gray above, without definite markings, dorsal and caudal darker than general ground tint, margins of pectoral and pelvic fins paler. Lower surface grayish or yellowish white, posterior corners of pectoral fins and tips of pelvic fins more or less dusky (Ref. 6902).

Biología     Glosario (por ej. epibenthic)

This benthic inshore species is found over soft bottoms to at least 50 m; feeds on benthic crustaceans and polychaetes. Gestation last about a year, produces litters of 1-8 pups in autumn (Ref. 114953). Ovoviviparous (Ref. 50449). Maturity size for males at 43-45 cm TL, females at 42-48 cm TL; birth size at 13-16 cm TL (Ref. 114953).

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).
