The Goby fish is a small, freshwater and marine fish belonging to the family Gobiidae. They are known for their unique body shape, which is typically elongated and slender. Gobies can be found in various habitats, including coral reefs, sandy bottoms, and estuaries. They often have a fused pelvic fin that forms a disc-like sucker, allowing them to cling to surfaces. Goby fish are diverse, with over 2,000 species identified worldwide. Many gobies are colorful and exhibit interesting behaviors, such as burrowing in the sand or forming symbiotic relationships with other marine creatures like shrimp. They primarily feed on small invertebrates and algae.
