Gobies are small fish belonging to the family Gobiidae, which includes over 2,000 species. They are typically found in both freshwater and marine environments, often inhabiting sandy or rocky substrates. Gobies are known for their unique body shape, which is usually elongated and features a fused pelvic fin that forms a disc-like structure, allowing them to cling to surfaces.
These fish play an important role in their ecosystems, serving as both prey and predator. Many species of gobies have interesting behaviors, such as forming symbiotic relationships with shrimp or living in burrows. Their diverse habitats and adaptability make them a fascinating group of fish.
