Biología     Glosario (por ej. epibenthic)

Common inshore (Ref. 6871) but reported to 440 m depth (Ref. 26346). Found in estuaries, lagoons, and around reefs (Ref. 12951). Reported to enter freshwater in Australia (Ref. 12951). Found on soft bottoms (Ref. 5578). Feeds on crabs, mantis shrimps, bivalves, polychaetes and conger eels (Ref. 5578). Ovoviviparous (Ref. 50449).

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). With young free swimming by 35 cm WD (Ref. 6871). Distinct pairing with embrace (Ref. 205).
