Fishes are diverse aquatic vertebrates, with over thousands of species described. They range in size from small cyprinid fish, such as the goldfish, to the giant oceanic catfish. Fishes live in the world’s oceans and many lakes and rivers. Some fishes are significant food sources for humans, and others provide valuable resources for recreation or industry.
Many fishes live in freshwater. Some freshwater fish species, such as the garter snake lizard, can live in fresh and saltwater habitats. Other fish, like the cichlid and palomino trout, are strictly freshwater. Finally, some fish only live in certain types of water, such as the anadromous salmon that swim upriver to spawn.
