is the function of the fish tail? 1. Provide power: For most fish, the tail is used to provide power. Fish live in the water and want to swim by wagging their tails to make themselves move forward. Of course, besides their tails, they also have the same effect by swinging their trunks. In addition, there are some strange fish that can use the dorsal fin to move forward, such as seahorses.
2. Control the direction: In addition to providing power to move forward, the tail can also control the direction of the fish. When it needs to turn left or right, it can use the tail to control it. If the fish loses its tail, it will not be able to turn. In addition, fish swim up and down by using the anal fin.
3. Increase the aesthetic feeling: The tail of fish can also increase its own aesthetic feeling, such as the tail of guppy and some goldfish. Besides being ornamental, the beautiful tail can also help them attract the opposite sex, so as to better mate and reproduce.
of fish tails? There are generally four types of fish tail fins. The first is a rounded caudal fin with only one lobe and a pointed end, which is generally used in embryonic and larval stages. The second is the crooked tail fin, which is divided into upper and lower lobes. The upper lobe is longer and the lower lobe is shorter. Chondrichthyes usually have this kind of fin. The third is the orthomorphic caudal fin, which also has two upper and lower lobes, but is completely symmetrical, which is also the characteristic of higher fish. The last one is the prototype caudal fin, which is rounded at the end, but not pointed, and belongs to the more primitive tail type.
