Some fish, like flying fish, jump out of the water to escape their predators or to travel short distances in the air using their pectoral fins as wings.
Some fish have developed the ability to fly out of the water due to specific evolutionary pressures related to their environment. Basically, it's evolution: individuals that jumped a bit out of the water had a better chance of avoiding being eaten and thus surviving to reproduce. As this behavior was repeated, fish with wider and stronger pectoral fins began to appear, facilitating this kind of gliding leap. This is how flying fish gradually specialized, permanently adopting this unusual but effective strategy. Today, jumping out of the water – even briefly – gives them a real advantage, whether for survival or to expand their territory.
Some fish, like the flying fish, use their ability to glide above the water as an effective escape technique in the presence of danger. When they detect a predator like a tuna or a dorado, their best survival instinct is to gain speed, quickly leap to the surface, and glide out of reach for several meters. Out of the water, they evade the sight of aquatic predators and gain valuable time. This unexpected aerial escape method surprises predators, causing them to lose precious seconds. It’s simple, quick, and incredibly clever.
Some fish, like the famous flying fish, completely leap out of the water to improve their chances of spotting food. By gaining altitude during their gliding jump, they have a much clearer overall view of nearby schools of small fish, shrimp, or plankton. This technique allows them to cover a larger area quickly, thus saving energy instead of swimming blindly for long periods. It's a bit like climbing a tree to see if there's anything interesting around rather than exploring every corner on foot. From above, reflections and movements on the surface often reveal the presence of potential prey, making their hunting easier.
Flying fish have developed some handy physical tricks to launch themselves into the air (well, out of the water!). First, their very special shape of pectoral fins: really broad, spread out like true wings, ideal for gliding for a few seconds or even tens of seconds above the waves. Then, there’s their powerful tail with an extremely muscular caudal fin, capable of providing the necessary thrust for the initial leap out of the water. In terms of body shape, they are streamlined and aerodynamic, somewhat like flying torpedoes, with a musculature concentrated towards the tail to boost their propulsion. Additionally, their rather smooth scales significantly reduce air resistance, facilitating this life-saving glide. Lastly, their lightweight due to a light skeleton and small size gives them a serious advantage in staying out of the water for as long as possible.
Flying fish typically live in marine environments where conditions are quite choppy, with frequent waves and strong winds. A strong wind is actually helpful, as it assists these fish in taking flight and gliding longer. The waves and marine turbulence allow them to gain momentum easily, and the updrafts carry them even further. Even temperature plays a role: when the water is warm, their metabolism is accelerated, enabling them to move faster and jump higher to get out of the water. Finally, certain climatic seasons intensify the presence of predators in specific areas, forcing these fish to adopt their aerial technique more frequently to quickly escape dangerous situations.
In certain places around the globe, such as Japan or Barbados, flying fish are part of the traditional menu. They are particularly enjoyed fried or prepared as sashimi!
Although referred to as 'flying fish', these animals do not actually flap their fins like a bird. Instead, they engage in a gliding flight that they initiate after a powerful leap out of the water.
Did you know that the flight path of flying fish is sometimes so unpredictable that even hunting seabirds can have difficulty catching them in mid-air?
The observed record for the flight of a flying fish is 45 consecutive seconds out of the water, covering nearly 400 meters in distance. Impressive, isn't it?
Even though this escape strategy carries certain risks (such as landing on a hard surface or becoming vulnerable to aerial predators), it generally compensates for these risks by providing a particularly effective chance to avoid more dangerous and immediate aquatic predators.
Yes, to a certain extent. By making subtle movements with their bodies and fins, these fish can slightly adjust their trajectory, allowing them to avoid a predator or an obstacle, and sometimes even extend their flying time by harnessing air currents above the waves.
Yes, in addition to flying fish, some squids or cephalopods are known to make short leaps out of the water to escape predators. Nevertheless, flying fish remain the most iconic due to their exceptional abilities to glide for long distances.
Flying fish do not have true wings in the strict sense, but rather large, well-developed pectoral fins that are adapted for their needs. These fins essentially allow them to glide through the air after gaining momentum out of the water.
The typical flight of a flying fish generally lasts from a few seconds to a maximum of about thirty seconds. Although most species rarely exceed ten seconds, some individuals can cover more than 200 meters in a single flight.
