Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Anal spines: 0; Anal 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): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00201 - 0.00824), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this species & 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).
