Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 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.
Presumed marine, pelagic and coastal, but at least the juveniles enter mangrove creeks of rivers, thus tolerating lowered salinities. More data needed.
