A fish is a water-dwelling vertebrate with gills that doesn't change form, as amphibians do, during its life. Most are cold-blooded, though some (such as some species of tuna and shark) are warm-blooded. There are over 29,000 species of fish, making them the most diverse group of vertebrates. Fishing is the activity of hunting for fish. Fishing is a very ancient practice that dates back at least to the Mesolithic period which began about 10,000 years ago.
