| The Characiformes are an order of ray-finned fish, comprising the characins and their allies. Grouped in 19 recognized families, there are probably about 2,000 species, including the well-known piranha and tetras. All species are exclusively freshwater. The vast majority live in tropical South America, with a few hundred species in Africa, and a few dozen in North and Central America.
