What kind of fish is winged fish? What does the difference represent?

There are three kinds of winged fish, namely flying fish, angel fish, sea bream, and Tanglin Nachong square leopard bream;

1.Flying fish is famous for its ability to fly, so it is called flying fish, but flying fish is not flying, it feels like it is flapping its winged fins, but in fact it is just gliding;

2.Angelfish, shakuji is a kind of cilid, is a representative fish of tropical fish, dorsal fin and pelvic fin are very slowly hidden, very similar to angel wings, native to the Amazon River in South America;

3.Seawall bream is a collective term for several species of marine fish in the family Seabream. Widespread in the world's moderately deep waters;

4.Oriental leopard bream is a fish of the genus Leopard bream in the family Leopard bream, commonly known as Dragonfly Horn, Gaswen, Flying Turtle Fish, Flying Tiger, and Flying Horn Fish.

The wings on the back of a fish are called dorsal fins.

The dorsal fin mainly plays a balancing role in the fish's body, and if the dorsal fin is cut off, the fish will roll over on its side and cannot stand upright. However, there are also some fish with long bodies, dorsal and anal fins, which can assist in body movement and propel the body forward rapidly. For example, the dorsal fin of a hairtail, the anal fin of an electric eel, and the dorsal and anal fins of a moray eel can all push the body forward.

For example, the seahorse with a special body shape also relies on the movement of the small dorsal fin to propel the body forward.

The results of studying the movement characteristics and kinematic parameters of the tail fin showed that the caudal fin swing frequency was when the carp swimming speed was long, the main movement of the caudal fin during the carp cruising was lateral oscillation, the shape of the caudal fin was periodically abducted and adducted, and the average swing of the tip of the upper leaf of the tail fin was about larger than that of the tip of the lower leaf of the tail fin.

Winged fish are flying fish. There are about 40 species of this fish, and the most important feature is that the pectoral fins are long, extending all the way to the tail, which looks like a pair of wings. It can jump out of the water and stay in the air for more than 40 seconds, and the maximum distance can even reach about 400 meters.

However, it doesn't really fly, but glides through the air, so that it can dodge attacks from other enemy creatures in the water.

Fish generally live in the water, only birds will have wings to fly in the sky, this is common sense in our lives, but it is not absolute, because some of the fish living in the water also have wings, but what is the name of this winged fish, many people may not know it, so I will briefly introduce you to this kind of winged fish.

1. Fish with wings.

This kind of winged fish has a particularly nice name called butterflyfish, because it is really very like a butterfly after its wings, of course, it also has another name called shallow sea bream, this kind of fish generally lives in the Atlantic Ocean, of course, it can also be seen in the Pacific Ocean and other places, especially in Australia or the coastal areas of Japan, it is able to catch such fish often.

2. Posture characteristics.

This fish is generally longer in size, and the color is very different from other fish, because its color is generally pink, and some are red, and in its appearance is relatively hard and some very fine scales, especially this pair of wings is very peculiar, it feels like a bird's wings, but this fish is not beautiful, although it has wings, but its appearance is very peculiar, and it can even be described as ugly, with big eyes, And it's still squinted, and the head is relatively large, but this fish can be eaten, and if you make it, it tastes very delicious.

Therefore, it is not necessarily birds that have wings, in fact, entertainment can also grow wings, which is really the world's greatest, and the fish with wings can still live very well in the water.

The "shark fin" in Lu Xun's "Take-it-ism" is a metaphor for something nutritious and valuable.

When you see shark fin, you don't throw it on the road to show its "civilianization", as long as you have nourishment, you and your friends regret eating it like radish and cabbage, and you don't use it to feast guests. Shark fin, as a relatively valuable ingredient, is not eaten by ordinary people in three meals a day, because it is high and cannot be bought by civilians.

Lu Xun used the big mansion as an example, and then used "shark fin" and "opium" as clever metaphors for objects that need to be chosen, which not only visualized abstract things, but also made the principle of the key to excitation more clear. The reason why Lu Xun was able to take such a vivid example is that he made meticulous observations and speculations on the truth to be demonstrated, the things used for metaphors, and the relationship between the two, and made a lot of analysis and research from this and the other, from the surface to the inside. It is precisely because of this that Lu Xun's essays are generally very vivid and have great artistic appeal.
