Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; brackish; pelagic-neritic; depth range 0 - 50 m (Ref. 189). Tropical; 5°S - 13°S, 132°E - 148°E (Ref. 189)
Western Central Pacific: Papua New Guinea (Fly River) and northern Australia (near Darwin).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.5 cm SL male/unsexed; (Ref. 189)
Dorsal spines (total): 0; Anal spines: 0; Anal soft rays: 32 - 29. Belly with 14 to 16 + 9 = 23 to 25 keeled scutes from isthmus to anus. Maxilla short, reaching to hind border of pre-operculum; first supra-maxilla short, about half length of second. Pseudobranch long. A diffuse dark saddle on nape; no dark blotch behind gill opening.
Body shape (shape guide): elongated; Cross section: compressed.
Presumed marine, pelagic and coastal, but at least the juveniles enter mangrove creeks of rivers, thus tolerating lowered salinities. More data needed.

Estimates based on models
Preferred temperature (Ref.
123201): 27.4 - 28.3, mean 27.9 °C (based on 84 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00181 - 0.01006), b=3.11 (2.93 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
