Eastern Pacific: Mexico to Peru, including the Galapagos Islands (Ref. 5530).

Short description
Dorsal spines (total): 9; Dorsal soft rays (total): 24 - 27; Anal spines: 3; Anal soft rays: 21 - 23. Description: Dorsal very blue-green or metallic blue, ventral silver or white; stripe (may be absent) yellow from gill opening upper end to caudal peduncle upper part; opercle edge with black spot. Body elongate and compressed moderately; profile, dorsal less convex than ventral. Eyes very large, shorter than snout length; adipose eyelid very well developed, covers the eye almost entirely. LL curved part equal or slightly shorter than straight part 0.7 to 1.3 times; LL scales 48-56 on curved part, 0-11 on straight part; LL scutes 29 to 42, small. Cleithrum with furrow, deep, ventral; large papilla immediately about furrow, small papilla near dorsal edge. Pectoral fins falcate; anal fins first two spines detached. (Ref. 2334, 55763, 90102)
Biology
Adults prefer clear oceanic waters around islands to neritic waters (Ref. 5217). Occasionally in turbid waters (Ref. 9283). Pelagic (Ref. 58302). Individuals travel in compact groups of hundreds of thousands of fish. Mainly nocturnal in habit, they disperse at night to feed on small shrimps, benthic invertebrates, and forams when inshore, and zooplankton and fish larvae when offshore (Ref. 9283, 90102). Marketed fresh and salted or dried (Ref. 9283). Reported to reach 70 cm TL (Ref. 48635).

Estimates based on models
Preferred temperature (Ref. 123201): 20 - 29.2, mean 27.9 °C (based on 6848 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.75 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.01211 - 0.01503), b=2.99 (2.96 - 3.02), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278): 3.8 ±0.2 se; Based on diet studies.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (K=0.6-0.9).
Prior r = 1.19, 95% CL = 0.79 - 1.79, Based on 8 data-limited stock assessments.
Fishing vulnerability (Ref. 59153): Low vulnerability (25 of 100).
Climate vulnerability (Ref. 125649): High vulnerability (60 of 100).
Price category (Ref. 80766): Very high; Reliable: based on ex-vessel price for this species.
