Why do flying fish fly out of the water? What are the natural enemies of flying fish

The reason why flying fish can fly out of the water has a lot to do with its body structure. Its pectoral fin, ventral fin and caudal fin are very developed, especially its pectoral fin, which is much wider and longer than other fish. The lower leaf of its caudal fin is longer than the upper leaf. Therefore, when it encounters enemies or is frightened, the pectoral fin will generate lifting force. With the driving force of the caudal fin when swimming, it can easily jump out and slide with the help of air. 1、 Why do flying fish fly? The pectoral fin of flying fish is particularly developed, about two-thirds of its length and one-third of its width. Its ventral fin is also very strong, and the lower leaf of the caudal fin is much longer than the upper leaf. These special structures give it the conditions to take off. When the pectoral fin generates a lifting force and cooperates with the forward thrust of the caudal fin, it can easily jump out of the water. After jumping out of the water, it will spread its wings and glide with the help of air. In addition, although it can fly, it is not flying all the time. Usually, it will fly out of the water to escape predators only when it is threatened. 2、 What are the natural enemies of flying fish? There are many natural enemies of flying fish. It itself can only grow to about 60 cm. Carnivorous fish larger than it will eat it. Although it is fast, there are always faster, such as swordfish, swordfish and tuna. These fish are faster than it, so it is very easy to prey. In addition to the in the water, many birds in the sky will also eat fish, such as seagulls. Of course, the most terrible enemy for it is mankind. 3、 Life habits of flying fish flying fish are distributed in warm sea areas all over the world. Although they have the ability to fly, they are easy to stay hidden. They can fly away from the water only when they are attacked or stimulated by the sound of the ship's engine. They can fly a high distance and even jump onto the ship's deck. It usually feeds on plankton and begins to lay eggs in April and may. （FeiYuWeiShenMeHuiFeiChuShuiMian，FeiYuDeTianDiYouNaXie）
