Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 200 cm WD macho/indeterminado; (Ref. 6678)
Found in tropical to warm temperate coastal waters, but absent from islands of western Pacific. Often forming large groups swimming near the surface and quite destructive of commercial oyster and clam beds. Feeds on bottom-living mollusks, crustaceans and fishes. Seldom marketed. Ovoviviparous, gestation period up to one year with 2-6 embryos produced.
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).
