Flying fish are known for their remarkable ability to leap out of the water and glide through the air for distances ranging from 50 feet (15 meters) to 1,000 feet (300 meters). This behavior helps them to escape from underwater predators like mackerel and swordfish — but also exposes them to aerial hunters such as seabirds.
They belong to the family Exocoetidae, which includes around 70 species. Some well-known species include the Atlantic flying fish (Cheilopogon melanurus), known for its long glides, and the Japanese flying fish (Cypselurus hiraii), often seen in the Pacific Ocean. Each species has unique adaptations that enhance their gliding abilities, such as varying fin lengths and body shapes.
In this article, we’ll delve deep into the flying fish’s appearance, diet, habitat, reproduction, and threats facing it. Moreover, we’ll look at some of the most interesting facts and answer frequently asked questions about this fascinating group of fish.
Appearance
The flying fish are small, typically measuring from 4 to 12 inches or 10 to 30 cm. Besides, they are known for their long, torpedo-shaped bodies, silvery or blue scales, and vertically forked tails.
However, the most prominent features of these long, slender fish are their wing-shaped pectoral fins that they use to self-propel themselves out of water. Sometimes, they are up to twice as long as the fish. Some flying fish also have another set of ‘wing,’ modified pelvic fins.
Another exciting feature is their large eyes and small mouths that help them to feed and lead their lives in peace.
Habitat
Flying fish are found mainly in the Atlantic, Pacific, and Indian Oceans. But you can find them in almost all of the world’s oceans, up to a depth of 650 feet. They are most common in tropical and subtropical waters.
They prefer to live in shallow coastal waters. That rightly implies that you can find them near coral reefs and other places in the ocean with plenty of vegetation.
Flying fish are rare in cold places because the weather interferes with the muscular function required to glide through the air.
These marine animals are common around the Caribbean to the extent that they are the national symbol of Barbados because the environment in this region is highly favorable.
Diet
Flying fish are opportunistic feeders. They primarily consume plankton, which includes a variety of microscopic plants and animals drifting in the ocean. They also feed on small crustaceans, such as copepods, and other tiny marine organisms.
These fish often forage near the surface, taking advantage of abundant food sources in warm, tropical waters. Their diet supports their high-energy lifestyle, enabling them to make impressive leaps out of the water to escape predators.
By feeding near the surface, flying fish play a crucial role in the marine food web, linking smaller organisms to larger predators.
Reproduction
Millions of flying fish congregate yearly for the spawning season. During this period, the females release plenty of eggs into the water. After fertilization, the fish attaches the eggs to floating debris or a piece of seaweed via a sticky filament. Once the larvae hatch, they swim and feed on their own.
These young ones can fly after reaching about two inches and can live for up to about five years.
Threats
Flying fish face several threats, including overfishing, habitat loss, and pollution of carbon sinks. They are also sometimes caught as bycatch in commercial fishing operations.
Many people also eat eggs as roe. Besides, these animals are mainly on their own after birth, exposing them to the risk of perishing. They gain the ability to fly after hitting about two inches.
Very few flying fish are at risk, though. The IUCN Red List classifies them as ‘Least Concern.’

- This fish can be kept in an aquarium.
- These marine animals have long, wing-like fins that they use to propel themselves into the air.
- They are an essential food source for many marine animals, including tuna, marlin, and dolphins.
FAQs
How many species of flying fish do we have?
There are close to 40 species of flying fish, which are spread across seven main groups. One of the most common ones is the blue flying fish. Its upper half is an iridescent blue. The black-wing flying fish, which is known for its dark blue, almost purple upper half, is the next. Four-wing flying fish is another common one, and it has four ‘wings,’ as the name suggests.
Why are flying fish an integral part of the world’s oceans?
They are an integral part of the food chain in most of the world’s tropical marine environments because they get nutrients from smaller prey, such as crustaceans. At the same time, they provide nutrients for larger predators, such as birds, squid, tuna, and marlins. This way, they ensure that all living things in tropical marine environments have access to enough food sources.
Do flying fish really fly?
When you hear about flying fish, you might think that this fish ray-finned fish with highly modified pectoral fins are capable of powered flight like many birds do. However, they can only propel themselves into the air at speeds of about 56km/hour for short distances. Depending on size, age, and the nature of the threat, these fish can propel themselves out of the water for distances ranging from 50 feet (15 meters) to 1,000 feet (300 meters).
How can you catch flying fish with ease?
Humans have been catching them easily over the decades since they are attracted to light. You can use a canoe filled with water and light attached to it. The light will lure plenty of flying fish to leap into the canoe, and they can’t get enough speed while inside the canoe to jump back into the water.
