? Fish scales are a structure that many fish have. They grow on the surface of the fish body and play an important role. But not all fish have scales. Some fish don't have scales on the surface of their bodies, but Mandarin fish is a scaly fish. Their body surface is covered with a layer of scales, but it is not particularly obvious, because their scales are very small and very thin, sometimes all the scales will just stick to the surface of their body, not very obvious. However, careful observation can still be seen, so we can not think that Mandarin fish is a fish without scales. The scales
of Mandarin fish, like those of other fish, play a very important role. The scales only stick to the surface of the body of the Mandarin fish, which can prevent the dirty things and harmful bacteria in the water from invading the Mandarin fish, so that they are not easy to get sick and protect their bodies. In addition, the scales also have the function of reflecting light, which can play a role when the Mandarin fish encounters natural enemies. However, if humans want to eat Mandarin fish, these scales should be removed, otherwise it will affect the taste. The specific operation is not particularly difficult, you can use vinegar, and then push down the fish scales.
? Teeth are also one of the important structures of fish and even all animals, which mainly play a role in their hunting and feeding activities. But not all fish have teeth. Some have no teeth. The Mandarin fish is a kind of fish with teeth, and they have teeth on both the upper and lower jaws. Teeth can also play a role for them. Mandarin fish are carnivorous fish. Their teeth can play a certain role when they hunt. In addition, their teeth can also play a role when they eat.
