Famous for their ability to leap out of the water, flying fish are able to glide long distances when airborne. Flying fish don't actually have wings; instead they have uniquely adapted fins that function in a similar, albeit less effective, way.
Flying fish live in the "sunlight zone" of the ocean, which isan area near the surface. Because this area is so commonlypopulated by predators due to the large abundance of smaller fishlife, flying fish developed their unique wing-like fins as adefense mechanism. These fins allow them to leap from the water andglide over 50 meters, and in doing so they often elude theirpredators.
