Consigli per l'identificazione

1. 1

   Eye Placement

   While typically right-eyed (dextral), a significant proportion (up to 30%) can be left-eyed (sinistral). This variability is a key characteristic.

2. 2

   Lateral Line

   Observe the lateral line, which has a distinct, strong curve above the pectoral fin. This helps distinguish it from other flatfish.

3. 3

   Skin Texture

   Feel the skin along the lateral line and at the base of the dorsal and anal fins for the presence of rough, bony tubercles or plates. This gives it a distinctly rougher feel compared to some other flatfish.

4. 4

   Coloration

   Note the variable dorsal coloration (olive-brown to grey-brown, often mottled) and the white blind side, sometimes with yellowish or brownish patches. Reddish spots may be present.
