Flying fish are widely distributed in warm waters all over the world and are famous for flying. They are all small, with winglike hard fins and asymmetrical forked tails. The jumping height is enough to make it jump on the deck of the ship on the water. Sailors often find flying fish landing on the deck at dawn.

Flying fish live in the upper layer of seawater and are the prey of all kinds of fierce fish. Flying fish fly mainly to avoid predators. Flying fish don't jump out of the water easily. Only when they are attacked or stimulated by the sound of ship engines can they display their flying skills.

The main food of flying fish in the sea is tiny plankton. Every April and May, it comes to China from the equator to breed. Its eggs are light and small, and the membrane on the surface of the eggs has filamentous protrusions, which is very suitable for hanging on seaweed.
