gobioids
Gobioids are a group of ray-finned fish belonging to the order Perciformes. This diverse clade encompasses several families, with the most prominent being the Gobiidae family, commonly known as gobies. Gobies are a vast and varied group, comprising over 2,000 described species. They are characterized by their fused pelvic fins, which form a suction disc, though this feature is reduced or absent in some lineages. Many species inhabit marine environments, particularly coral reefs and rocky shores, where they often live in association with other organisms like shrimp or corals. Freshwater and brackish water species are also common.
Gobioids exhibit a wide range of sizes and appearances, from tiny reef-dwelling species to larger bottom-dwellers.
