Identification Tips

1. 1

   Body Coloration

   Look for the overall silvery sheen, which can sometimes have a yellowish tint on the back. Faint vertical bars may be visible, especially on live specimens.

2. 2

   Caudal Spot

   The most reliable identification feature is the distinct, dark, saddle-like spot on the caudal peduncle that extends onto the base of the caudal fin. This spot is usually very prominent.

3. 3

   Fin Spines

   Count the dorsal fin spines (11-12) and anal fin spines (3) to confirm identification within the Sparidae family.

4. 4

   Mouth and Teeth

   Observe the small mouth with incisor-like teeth at the front, used for nipping, and molar-like teeth in the back, used for crushing.
