The first thing to talk about is flying fish. Flying fish live in the ocean, belonging to the fish of the order Animalidae, also known as rays. It has a pair of specially developed pectoral fins, which spread like wings and can often fly forward out of the water. Of course, that is often when it encounters enemy harm.
Before taking off, the flying fish will swing its tail vigorously, and then rush out of the water after swinging for a while, and then use the sea breeze to push the upward airflow of the waves forward, blowing under its two huge pectoral fins and holding it forward to fly.
If flying fish fly on the sea and a sea breeze blows from the side, it can make flying fish fly in a straight line and draw a big arc around the corner. If it happens to meet a ship in the process of flying, and the sea breeze hits the ship's side, the wind will rush up and bring the low-flying fish up to the deck. There is no updraft on the ship, so the flying fish can't fly, and they fall on the deck one after another.
Among mammals, bats, flying squirrels, marsupials, flying monkeys, etc. also have the ability to fly.

Zombies live in the forests of northeastern and southern provinces of China. They can glide freely in the forests. Whenever they fly, they climb to the top of the tree and then glide down. When it glides, it should spread its limbs horizontally, and its tail is straight and upturned. There is also a scream in your mouth, as if to cheer yourself up. After they jumped into a tree, they immediately climbed to the top of the tree. Why? It turns out that they are preparing for the next flight. The marsupial lives in Australia, and it also has skin wings, which can fly down from a height of 20 to 30 meters. Flying monkeys live in Malaysia, Indonesia and the Philippines, and there are membranes between their limbs and tail. Its flying technology is much better than that of flying squirrels. Not only does it fly farther than them, but its footprint can fly more than 100 meters, and it can flexibly control the direction and height of flight. It is worth mentioning that this animal's life habit is very bizarre. When resting, sleeping or swallowing food, it likes to hang upside down on the branches.
Of course, the famous aviator among mammals should be the bat. Its forelimbs, hind limbs and tail are connected with a developed skin membrane. Its collarbone is quite developed, and its phalanges are particularly long. The hind knee joint can be backward and the soles of the feet are forward. They hide in caves and old houses during the day, rest upside down, and come out to look for food at night. Although their flight can't be compared with that of flying animals, it is enough to help them find food directionally. According to the information currently available, about 900 species of bats can fly all over the world.
Mammals are like this, so what about flying without wings in reptiles?
In tropical forests such as Java and Borneo, there is a species called Feilong, whose body length is less than 10 cm, but its body side has an orange-red slightly yellow-green skin membrane, which is supported by five specially extended ribs. Its body side skin membrane can help it glide between branches.
Before each flight, it sucks in a lot of air to make its body swell, thus making its specific gravity lighter. At this time, it will fly down from the top of a high tree, land on another tree, and then climb to the top of the tree. As soon as you see flying insects, you quickly rush to prey. Its biggest feature is that it can catch insects while flying, and it can also fly left and right.
In some forest areas of Borneo, flying frogs bring people a beautiful landscape. The flying frog has a flat body, developed webbed between its long toes, and suckers at each toe. These suckers are unusual because there is a lot of mucus in them. This special device enables it to jump and climb briskly between branches. When it jumped down from the tree, it had sucked in the air like a dragon. When it fell, it could hold up four small parachutes around its body. The flying frog is different from Yu Feilong in that it can jump from the flat ground to a tree 1 to 2 meters high. Of course, it has another feature that can't be ignored: when it is in the water, it will push into the water with two big webbed hind legs, and then it can jump out of the water directly. It should be noted that the flying animals in reptiles and mammals are not really flying, they just delay the landing time after jumping.
Other invertebrates also have this flying ability, such as butterfly moths and migratory locusts in arthropods, and they can dance!
