Tunnistusvinkit

1. 1

   Dorsal Fins

   Look for two clearly separated dorsal fins. The first is spiny and the second is soft-rayed. This distinguishes it from single-dorsal fin species like pike.

2. 2

   Eyes

   Observe the large, often glassy or reflective eyes, which are an adaptation for hunting in low light or turbid conditions.

3. 3

   Teeth

   Carefully check for prominent canine teeth in both jaws, a key predatory feature.

4. 4

   Coloration and Bands

   Note the greenish-grey back, silvery belly, and the presence of 8-12 faint, darker vertical bands on the flanks. These bands are less distinct than those of a European perch.

5. 5

   Body Shape

   Its elongated, torpedo-like body is more slender than that of a European perch but less elongated than a pike.
