Max length : 40.0 cm TL macho/indeterminado; (Ref. 114953)
Found in continental shelf in shallow water to at least 15 m deep. Presumably feeds on small invertebrates and fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Males mature at ca. 32 cm TL, females at ca. 35 cm TL (Ref. 114953).
Ciclo de vida ou comportamento de acasalamento
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).
