Biology     Glossary (e.g. epibenthic)

Adults inhabit lagoons, estuaries and freshwater (Ref. 6028, 48637, 79840). They occur in the lower reaches of freshwater streams, usually on mud bottoms (Ref. 44894). Juveniles are found mainly among mangrove roots in the more saline areas of lagoons and estuaries (Ref. 6028, 79840). Carnivorous (Ref. 79840). Marketed fresh (Ref. 12693).
