Consigli per l'identificazione

1. 1

   Mouth Size

   The most distinguishing feature: the upper jaw (maxilla) extends well past the posterior margin of the eye when the mouth is closed. This is a key differentiator from Smallmouth Bass.

2. 2

   Dorsal Fin

   The dorsal fin is deeply notched, almost appearing as two separate fins. The spiny anterior portion is clearly separated from the soft-rayed posterior portion.

3. 3

   Lateral Stripe

   Presence of a prominent, often broken or blotchy, dark lateral stripe running horizontally along the body. This stripe can be more or less distinct depending on water clarity and habitat.

4. 4

   Scales on Opercle

   The opercle (gill cover) is typically scaled, but the preopercle (bone in front of the opercle) is usually scaleless or has very few scales. This can be a subtle but useful identification point.
