Beloniformes

• abstract: The Beloniformes are an order of six families of freshwater and marine ray-finned fish: the Adrianichthyidae (ricefish and medakas); Belonidae (needlefish); Exocoetidae (flyingfishes); Hemiramphidae (halfbeaks); the Scomberesocidae (sauries) and the Zenarchopteridae (viviparous halfbeaks). With the exception of the Adrianichthyidae, these are streamlined, medium-sized fishes that live close to the surface of the water feeding on algae, plankton, or smaller animals including other fishes.
