Corpore compressissimo, lato; linea laterali antice sursum arcuata, angulata; pinna caudali parva, cauda angustissima; pinnis pectoralibus ad pinnae analis insertionem usque extensis; capite parum longiore quam alto. Caput compressissimum supra carinatum, parum longius quam altum, quartam totius longitudinis partem superans, antice declive; rostrum obtussimum, mandibula angustior quam in Carange lato, parum prominens; dentes mandibulae externi omnes ejusdem magnitudinis, retrorsum reclinati, parum minores quam illae maxillae superioris, quorum anteriores posterioribus duplo majores, aculissimi. Buccae planae nee non operculi et praecoperculi pars superior squamis minutissimis tectae. Oculi magni supra et ante maxillarum commissuram. Nares utrinque duae, rostri cantho propriores quam oculis, posteriores majores, ovatae, patulae, anteriores minores rimaeformes, subtulosae. Truncus compressissimus ovatus, postice rectis fere lineis in caudam tenuissimam angustatus, non duplo latior qual longus. Squamae omnes adeo parvae sunt, ut oculi inermi vix conspici possint, simplicissimae oblongae, lineis curvis concentricis minus confertis quam in Carange lato, notatae; radiis nullis.

Pinna caudalis parva, tenuis. Pinnae analis mollis radii anteriores sequentibus multo longiores; aculei antici subdistincti, breviores quam in Carange lato; pinnae ventrales parvae, obtusae; pectorales acuminatae, ensiformes, angustae. Pinnae pectorales radiis I8, ventralis 6, analis 2, 20, caudalis 7, 15, 7, dorsalis 8, 24. Supra caeruleus; latera et venter argentei.

Migratory: yes. Diadromous migration (anadromous)
Causality_of_migration: Trophic migration

Life cycle

A pelagic schooling species usually found in offshore reefs. Juveniles are encountered along shores of sandy beaches, also over muddy bottoms. May penetrate into brackish water and ascend rivers. Adults feed on fishes, shrimps, and other invertebrates. Often approach divers. Eggs are pelagic.
Reproduces via dioecism (sexes are separate), fertilization is external with an unknown spawning frequency in June, July, and August off Cuba.
Fecondity_number of eggs per adult: > 1,000,000
Ferility_period: Seasonal (during spring and summer) (April, July and August)
Spawning_method: External fertilization in the water column
