Environment: milieu / climate zone / depth range / distribution range
Brackish; pelagic; amphidromous (Ref. 51243). Tropical; 21°N - 13°N, 80°E - 90°E (Ref. 189)
Indian Ocean: Godavari estuary on the eastern coast of India only, but presumably more widespread.

Morphology | Morphometrics
soft rays: 31 - 32. Belly with 16 to 18 + 10 or 11 = 26 to 29 keeled scutes from isthmus to anus. Maxilla moderately short, tip pointed and reaching just to edge of gill cover; first supra-maxilla absent. Serrae on lower gill rakers not clumped. Tip of pelvic fin falling short of vertical from dorsal origin. A dark `saddle' on nape, extending to area behind upper part of gill opening.
An estuarine species, but there is no indication if this signifies a marine or riverine fish.

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00184 - 0.00988), 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 ±0.5 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).
