Dicas de identificação

1. 1

   Snout Projection

   The most reliable distinguishing feature is the snout extending noticeably beyond the lower jaw. This is a key characteristic of the genus Anchoa.

2. 2

   Maxilla Length

   Observe the maxilla; in Anchoa lyolepis, it extends to or beyond the posterior margin of the preoperculum, but typically not as far as in some other Anchoa species.

3. 3

   Lateral Stripe

   The presence of a distinct, often silvery or iridescent, lateral stripe is a good indicator, though its prominence can vary.

4. 4

   Body Shape and Size

   Its slender, elongated body and small adult size (usually under 15 cm) help differentiate it from larger clupeiforms.
