Ecologia
marinhas; Água doce; estuarina bentopelágico; catádromo (Ref. 51243). Tropical; 3°S - 14°S, 135°E - 149°E (Ref. 55)
Oceania: known only from southern Papua New Guinea between the Port Moresby district and the Fly River.
Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 100.0 cm TL macho/indeterminado; (Ref. 55); common length : 60.0 cm TL macho/indeterminado; (Ref. 55); peso máx. publicado: 19.2 kg (Ref. 40637)
Espinhos dorsais (total) : 10; Raios dorsais (total) : 13 - 14; Espinhos anais: 3; Raios anais : 8. Dorsal profile of head steeply sloped. Preorbital bone relatively broad, usually much greater than eye diameter. preopercular notch and knob poorly developed. Scale rows on back parallel to lateral line anteriorly. There are distinct color phases with the entire body blackish or with a series of 6 or 7 broad greyish bars on sides. Juveniles usually banded (Ref. 48635).
Adults inhabit large freshwater streams. Not reliably reported from marine habitats but may occur in estuaries. Larval stages are probably marine. Juveniles of adolescent fish may occur in mangroves and could be mistaken for the mangrove jack L. argentimaculatus that has a similarly banded pattern in such habitats (Ref. 48635). It is a popular sport fish forming the basis of a safari-angling industry.
