California flying fish

The California flying fish (Cypselurus californicus) is a large species of oceanic fish found in the open seas off the coast of southern California and adjacent Mexico. Flying fish, in general, belong to the family Exocoetidae and are known for their gliding ability rather than true flight. They build speed underwater, then break the surface, spreading their enlarged pectoral and/or pelvic fins to glide through the air. This gliding is a primary defense mechanism to escape predators. While some flying fish are "two-winged," the California flying fish is considered "four-winged" due to enlarged pectoral and pelvic fins.12
