Dicas de identificação

1. 1

   Pelvic Fin Disc

   The most definitive characteristic is the fused pelvic fins forming a suction cup. This distinguishes them from blennies, which have separate pelvic fins.

2. 2

   Dorsal Fins

   Gobies typically have two distinct dorsal fins, the first spiny and the second soft-rayed. The separation or proximity of these fins can be a key identifier for species.

3. 3

   Body Shape and Coloration

   Observe the overall body shape (often robust and elongated), head size, and specific color patterns, spots, or bands, which are species-specific.

4. 4

   Lateral Line

   The lateral line system in gobies is often reduced or absent on the body, but well-developed on the head, consisting of sensory pores and papillae patterns useful for identification.
