Description

The mirrorwing flyingfish is a flyingfish (Exocoetidae) from the warm parts of the world ocean. The species grows to about 30 cm and has a slender, silvery body with greatly enlarged, wing-like pectoral fins. When threatened it shoots out of the water and glides on these 'wings' for tens of metres through the air to escape predators. It lives at the surface of the open ocean and feeds on zooplankton. It spawns year-round in warm water; the eggs have sticky filaments with which they attach to floating material. The species is harmless to humans.
