Dicas de identificação

1. 1

   Snout

   The snout is notably pointed and projects beyond the tip of the lower jaw, a key characteristic of the genus Anchoa.

2. 2

   Silvery Stripe

   A prominent, iridescent silvery stripe runs along the flank from the gill cover to the caudal fin base. This stripe is often more distinct than in some other anchovy species.

3. 3

   Pectoral Fin Length

   The pectoral fins are relatively short, not reaching the pelvic fin origin, which helps distinguish it from species like Anchoa hepsetus (Striped Anchovy) where the pectoral fin is longer.

4. 4

   Anal Fin Origin

   The origin of the anal fin is typically below or slightly behind the posterior base of the dorsal fin.
