Consigli per l'identificazione

1. 1

   Body Shape and Coloration

   Look for the robust, elongated body with a high back and the characteristic dark brown to coppery-brown dorsal coloration fading to a silvery belly. The overall dark appearance is a key identifier.

2. 2

   Dorsal Fin

   Observe the single, deeply notched dorsal fin, separating the spiny and soft-rayed portions. This is typical for Sciaenidae.

3. 3

   Lateral Line

   The lateral line is prominent and curves upwards anteriorly, then runs straight to the caudal fin. It is often darker than the surrounding body.

4. 4

   Mouth and Chin

   Note the subterminal mouth and the presence of a small, often inconspicuous, barbel on the chin, which is a characteristic of some sciaenids.
