Morphology | Morphometrics
soft rays: 7. When fresh, upper surface of head and trunk silvery, golden-brown, grading to silver on abdomen. Pelvic and anal fins yellow, first few rays of pelvic fin with a white distal margin or whitish-hyaline posteriorly; caudal fin yellowish-dusky with slightly whitish lower margin posteriorly, lobes usually broadly rounded posteriorly; dorsal and pectoral fins yellowish-hyaline; trunk with approximately 6-10 vertical dusky bars (about half width of pupil diameter), more apparent when stressed or when preserved. Number of scales between the base of the 5th dorsal fin spine and lateral line 4-4.5. Second dorsal fin spine longest, 23-27% SL (mean 25%). Supraneural bones 3 (Ref. 41102).
Specimens collected in shallow coastal or estuarine areas (Ref. 41102).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.3 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.).
Vulnerability (Ref. 59153
): Low vulnerability (16 of 100) .
