Tanımlama İpuçları

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 pike (single dorsal fin) and perch (two dorsal fins, but often closer together and less distinct).

2. 2

   Teeth

   Examine the mouth for prominent, sharp canine teeth, particularly on the lower jaw. This is a key predatory adaptation.

3. 3

   Body Shape and Coloration

   Note the elongated, torpedo-shaped body and the greenish-grey to brownish-grey back with silvery sides, often with faint vertical bars. The eyes can appear glassy.

4. 4

   Opercular Spine

   Feel for a sharp spine on the posterior edge of the operculum (gill cover).
