Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Épines anales: 0; Rayons mous anaux: 22 - 25. Snout short, about 1/2 eye diameter; maxilla shorter than in most other Anchoa species, tip pointed, not reaching beyond hind margin of pre-operculum; gill cover canals of walkeri-type. Pectoral fins large, reaching about pelvic fin origin; anal fin fairly long, its origin below or just before midpoint of dorsal fin base. A silver stripe along flank, less than eye diameter.
Body shape (shape guide): elongated; Cross section: oval.
Presumably schooling along beaches and down to 22 m. A single specimen was recorded from Coqueiros at the mouth of the Paraguaçu River, thus able to tolerate lowered salinities. More data needed.
