Dicas de identificação

1. 1

   Orange Spots

   The most reliable distinguishing feature is the presence of bright orange or reddish spots on the dark, eyed side of the body. These spots are usually distinct and often have a pale margin.

2. 2

   Bony Ridge/Tubercles

   Feel for a distinct bony ridge or a series of 4-7 bony tubercles (ossifications) running in a straight line from the back of the upper eye towards the lateral line. This is a key tactile and visual identifier.

3. 3

   Smooth Skin

   Run your hand over the eyed side; the skin should feel smooth due to the embedded cycloid scales, unlike some other flatfish with rougher ctenoid scales.

4. 4

   Eye Position

   Confirm that both eyes are on the right side of the head (dextral), which is characteristic of the Pleuronectidae family.
