Marine; pelagic-neritic. Tropical; 21°N - 4°N, 69°E - 90°E (Ref. 189)
Indian Ocean: eastern and western coasts of India.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 19.1 cm TL male/unsexed; (Ref. 117046)
soft rays: 35 - 39. Belly with 15 to 17 + 9 or 10 = 25 to 27 keeled scutes from isthmus to anus. A distinct hump at nape; tip of snout above upper rim of eye. Maxilla short, not quite or only just reaching to edge of gill cover; first supra-maxilla minute, oval. A dark blotch behind upper part of gill opening.
Presumably schooling. Undoubtedly confused with other species in the past. More data needed.

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
): 3.4 ±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).
