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).

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