Biologie     Verklarende woordenlijst (b.v. epibenthic)

Found inshore (Ref. 9862). Inhabits mangrove creeks and protected sandy channels to a depth of at least 18 m; relatively uncommon (Ref. 37816). Active swimmer, travelling long distances; feeds on crustaceans and molluscs (Ref. 68964). Ovoviviparous (Ref. 50449). Caught occasionally by bottom trawl, tangle net and inshore gillnet fisheries. Utilized for its meat, but of limited value as it is not frequently landed (Ref. 58048). Presumably utilized for human consumption in the western central Pacific (Ref. 9862).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

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).
