Consigli per l'identificazione

1. 1

   Pelvic Fins

   The most definitive characteristic is the fused pelvic fins forming a suction cup. This immediately distinguishes gobies from most other fish families.

2. 2

   Dorsal Fins

   Presence of two distinct dorsal fins, the first spiny and the second soft-rayed, is a key feature. The separation or proximity of these fins can help differentiate species within the genus.

3. 3

   Body Shape and Coloration

   Generally elongated bodies with cryptic coloration. Observe the specific patterns, spots, and banding, as these are often species-specific.

4. 4

   Head and Mouth

   Relatively large head and mouth. The position of the eyes (often high on the head) can also be a clue.
