Fish are aquatic vertebrate animals that have gills and fins. They are found in all bodies of water, from freshwater lakes and rivers to saltwater oceans. Fish come in all shapes and sizes, from the tiny dwarf goby, which is only about 0.4 inches long, to the enormous whale shark, which can grow up to 65 feet long.
Fish play an important role in the ecosystem by helping to control the population of other aquatic animals and by providing a food source for many other animals, including humans. Fish are also a popular recreational activity, with millions of people fishing for sport around the world.
