Biology     Glossary (e.g. epibenthic)

Inhabits inshore waters (Ref. 9862). Often found in brackish waters (Ref. 4832). Ovoviviparous (Ref. 50449). Caught occasionally by bottom trawl and inshore demersal gillnet fisheries off Jakarta. Utilized for its meat, but of limited value due to its rarity and small size (Ref.58048).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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).
