Ecología
marino; agua dulce; salobre bentopelágico; catadromo (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.
Tamaño / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 100.0 cm TL macho / no sexado; (Ref. 55); common length : 60.0 cm TL macho / no sexado; (Ref. 55); peso máximo publicado: 19.2 kg (Ref. 40637)
Espinas dorsales (total) : 10; Radios blandos dorsales (total) : 13 - 14; Espinas anales: 3; Radios blandos anales: 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.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00706 - 0.03101), b=2.97 (2.81 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 4.2 ±0.7 se; based on size and trophs of closest relatives
Resiliencia (Ref.
120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
