Consigli per l'identificazione

1. 1

   Opercular Spot

   Look for the prominent black spot on the opercular flap (gill cover) with a distinct bright red or orange margin. This is the most reliable distinguishing feature from other sunfish species.

2. 2

   Body Coloration and Markings

   Observe the iridescent blue-green wavy lines on the head and operculum, and the numerous iridescent spots (blue, green, orange, red) scattered over the body. The overall body is deep and compressed.

3. 3

   Mouth Size

   The mouth is relatively small, not extending past the front of the eye when closed. This differentiates it from larger-mouthed sunfish like the Largemouth Bass (Micropterus salmoides).

4. 4

   Pectoral Fins

   Note the long, pointed pectoral fins, which are typically longer than those of many other sunfish species.
