(total): 5 - 17;
soft rays: 8 - 11. Distinguished by the following characteristics: Pelvic frenum lacking or only visible with
magnification; in males, Dl height moderate, its margin almost straight, no stripe on fin only a few pale blue spots in life, white spots in preservative, all spines extend beyond membrane and first spine more than twice as long as others, dorsal fins contiguous, connected by membrane; in females, Dl negligible, represented by only a few short spines; D2 in both sexes lacking stripes; D 1 with 4-16 spines; longitudinal scale count 46-52; head width 15.4-19.4% SL; pelvic fin length 15.0-17.1 % SL ; length of anal fin base 14.2-18.5% SL; lengthofD2 base 20.6-26.8% SL; total D2 elements 11-14; total anal fin elements 9-12; TRDB 12-17 (Ref. 5218).
Facultative air-breathing (Ref. 126274); Inhabits brackish mangroves including the margin of estuaries and tidal creeks. Also penetrates the lower, tidal portions of freshwater streams (Ref. 44894). Appears to be restricted to tidal fresh waters in areas of mangrove and nipa palms (Ref. 2847). Amphibious air-breather (Ref. 31184).
