The Astonishing Abilities of Flying Fish

Flying fish, scientifically known as exocoetidae, are a fascinating species of marine ray-finned fish that belong to the order beloniformes. These creatures have gained the colloquial name of flying fish or flying cod due to their unique ability to make self-propelled leaps out of the water. While they do not fly in the same way birds do, their long wing-like fins enable them to glide for considerable distances above the surface of the water. This behavior is mainly attributed to their need to escape from underwater predators such as swordfish, mackerel, and marlins, as well as avian predators like frigate birds.

The Enigma of Flying Fish

The term “exocoetidae” serves as the scientific name and general name in Latin for flying fish. The suffix “-idae,” commonly used to indicate a family, is derived from the Latin word “exocoetus,” which is a transliteration of the ancient Greek name “ἐξώκοιτος.” This name was given to flying fish because people believed that they left the water to sleep ashore or flew and unintentionally became stranded in boats.

A Diverse Family of Flying Fish

The exocoetidae family comprises four subfamilies and seven genera. These include the exocoetinae subfamily, which features the genus fodiator; the parexocoetinae subfamily, home to the genus parexocoetus; the cypsellurinae subfamily, which includes the genera cheilopogon, cypselurus, hirundichthys, and prognichthys; and the fodiatorinae subfamily, which contains the genus fodiator.

The Adaptations for Flight

Flying fish are commonly found in tropical and warm subtropical waters across all oceans, particularly in the epipelagic zone. They possess various morphological features that enable them to leap above the ocean’s surface. One such feature is fully broadened neural arches, which provide stability and strength to their bodies during flight. These arches act as insertion sites for connective tissues and ligaments, creating a strong link between the vertebral column and cranium. Additionally, flying fish have well-developed vertebral columns and ossified caudal complexes, giving them the necessary strength to lift their bodies out of water and glide remarkable distances. Their pectoral fins are folded at the end of each glide to re-enter the sea or to change direction. The curved profile of their wings is comparable to the aerodynamic shape of a bird’s wing, enabling them to increase their time in the air by exploiting updrafts created by air and ocean currents.

Flying Fish: Predators and Prey

Flying fish feed mainly on plankton and serve as prey for dolphins, tuna, marlins, birds, squid, and porpoises. These creatures have evolved unique mechanisms and skills to evade predators and survive in their marine ecosystems.

A Rich Culinary Tradition and Cultural Symbol

Flying fish hold significant cultural and culinary value in many regions. In Barbados, they are considered the national symbol and are integral to various aspects of Barbadian culture. The country is even known as “the land of the flying fish.” In Japanese cuisine, flying fish are preserved by drying and used to make fish stock for dishes like dashi broth. The roe of the Japanese flying fish, known as tobiko, is used in sushi. In the Solomon Islands, fishermen catch flying fish using nets held from outrigger canoes, attracting them with torches.

Looking Beyond the Surface

The incredible abilities and adaptability of flying fish make them a truly remarkable species. Their unique evolutionary traits have fascinated scientists, who have even studied them as potential models for developing airplanes. As we delve deeper into the mysteries of the natural world, these extraordinary creatures continue to inspire curiosity and awe.
