Flying fish are a fascinating group of fish known for their unique ability to glide above the water’s surface. They belong to the family Exocoetidae and are found in warm tropical and subtropical waters around the world. These fish have developed special adaptations that enable them to take to the air and “fly” for short distances.

Flying fish use a unique launching technique to take flight. They build up speed underwater by rapidly beating their tails, and then propel themselves out of the water using a burst of energy. Once in the air, they spread their pectoral fins and glide above the water’s surface. Some species can stay airborne for several seconds, covering distances of up to 200 meters or more.

How much does a flying fish weigh?

The weight of a flying fish varies depending on the species, but generally ranges from a few grams to about 2 ounces (57 grams). The largest flying fish on record was 16 inches (41 cm) long and weighed 2 pounds (907 grams)³.
