Sailfin flying fish

The sailfin flying fish (Parexocoetus brachypterus) is a member of the flying fish family (Exocoetidae). As is typical of other members of its family, this species has the ability to jump out of the water and glide on hypertrophied fins in order to evade predators. It is considered a “two-winged” flying fish, meaning that it only has enlarged pectoral fins, as opposed to “four-winged” flying fish, which have both enlarged pectoral and pelvic fins.
