Tanımlama İpuçları

1. 1

   Body Shape and Coloration

   Look for the torpedo-shaped body, dark metallic blue-green back, and silvery sides. The most reliable visual cue is the distinctive pattern of 5-11 dark, oblique stripes on the back, slanting downwards and forwards.

2. 2

   Finlets

   The presence of small finlets behind the second dorsal and anal fins is a key characteristic of Scombridae, including Sarda sarda.

3. 3

   Corselet

   Feel for the patch of larger, thicker scales (corselet) around the pectoral fin and along the lateral line, contrasting with the otherwise scaleless body.

4. 4

   Teeth

   Examine the mouth for small, conical teeth arranged in a single row in both jaws.
