What is the role of a fish tail and what are the types of fish tails

Power: Fish swim in the water, mainly by the swing of the tail and torso to move forward, which is also the main function of the tail. Control Direction:

In the process of swimming, the fish can turn by waging its tail, and if it loses its tail, the fish can only swim straight. Increase aesthetics: In addition to being ornamental, it can also play a role in attracting the opposite sex to the fish.

1. Provide power: For most fish, the tail is used to provide power. Fish live in the water, and if they want to swim, they have to move themselves forward by wagging their tails, and of course, in addition to their tails, they also have the same effect by swinging their torsos.

In addition, there are some fish with strange structures that can advance through dorsal fins, such as seahorses.

2. Control direction: In addition to providing power for moving forward, the tail can also control the direction of the fish, when it needs to turn left or right, you can use the tail to control, if the fish loses its tail, it will not be able to turn. In addition, the upstream and downstream movements of the fish are achieved by using the anal fins.

3. Increase beauty: The tail of fish can also increase its own beauty, such as the tail of guppies and some goldfish, in addition to being ornamental, a beautiful tail can also help them attract the opposite sex, so as to better mate and reproduce.

There are generally four similar tail fins in fish. The first is a round caudal fin, with only one lobe, and the end is relatively pointed, which is generally used in the embryonic and larval stages. The second type is the crooked caudal fin, which is divided into upper and lower lobes, the upper lobe is longer and the lower lobe is shorter, and cartilaginous fish are usually this type of fin.

The third type is the regular caudal fin, which is also the upper and lower lobes, but perfectly symmetrical, which is also characteristic of higher fishes. The last type is the original caudal fin, which has a rounded end but is not pointed, and belongs to the more primitive tail type.

The most basic role of a fish's tail is to propel the body forward and control the direction.

The tail of some fish has a special role, such as the tail of a male guppy and the tail of a peacock can help it attract the opposite sex, and the tail of the fish can be used as a self-defense ** to protect the body.

The tail of a fish has four functions:

1. It can provide the impetus to move forward. Because the swim bladder is in the front part of the fish's body, the fish can float in the water by relying on the swim bladder, which rises by inflation and sinks by deflating, and it needs to cooperate with its tail.

2. Control the direction of swimming. For fish, the tail fin is far more important than other fins, and the loss of other fins will affect the balance of the fish, but after losing the tail fin, it will not be able to turn for the rest of its life.

3. Attract the opposite sex. Some fish tails look very beautiful, and they are still a weapon to attract the opposite sex, so that they can be better paired and reproduced.

4. Self-defense. Stingray tails can be used as self-defense**.

The tail of the fish keeps the fish balanced.

The role of the fish's tail is to propel the body forward and adjust the direction, maintain the balance of the body in the water, and provide forward momentum.

The most basic role of the fish's tail is to push the body forward and control the direction, as well as to maintain balance with the pectoral fin, because the swim bladder is in the front part of the fish's body, and the reason why the fish can float in the water is the swim bladder.

The most basic function is to propel the body forward and control the direction, which is equivalent to using the tail as a rudder to orient and maintain balance with the pectoral fin. There are also some fish whose tails have special functions, such as the tail of a male guppy and the tail of a peacock that help it attract competing opposite sex, and the tail of a stingray can be used as a self-defense**.

In addition, the tail of some fish has some special functions, such as the tail of a male guppy and the tail of a peacock to help it attract the opposite sex, and the tail of a stingray can be used as a self-defense**.

The tail of the fish is used to change direction, and the rudder of the ship is the same meaning.
