Short description Identification keys | Morphology | Morphometrics

Lateral line complete; 1 scale row between lateral line and pelvic-fin origin; 13-14 predorsal scales; dorsal-fin origin behind insertion of last pelvic-fin ray; distance between dorsal-fin origin and middle of caudal-fin base equal to distance between middle of eye and dorsal-fin origin; dark lateral stripe from upper extremity of gill-opening to caudal-fin base, more intense posteriorly, continued on caudal fin by a small black spot at base of median rays; dorsolateral stripe present, separated from dark lateral stripe by narrow light lateral stripe; 1.5-2 scales along dorsal midline between base of last dorsal-fin ray and vertical through anal-fin origin; caudal fin light yellow in life, with a very thin posterior dark margin (Ref. 36949).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00189 - 0.01159), b=3.08 (2.86 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 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).
