Flying fish

Flying fish is the common name for members of the family Exocoetidae in the order Beloniformes of the class Actinopterygii. About 64 species are grouped in seven to nine genera. Flying fish can make powerful, self-propelled leaps out of water into air, where their long, wing-like fins enable gliding flight for considerable distances above the water's surface. This uncommon ability is a natural defense mechanism to evade predators. Members of this family live in all the world's oceans, and are popular foodstuffs in many countries.
