Vertebrates and invertebrates are two different animals. The difference between them is whether they have a spine. Fish are vertebrates, which are ancient vertebrates, and they have a backbone. Carp, as a kind of fish, also has a backbone. Their backbones are made up of a few vertebrae. The spine plays an important role in carp's activities, allowing their bodies to move freely and flexibly. There is also a spinal cord in the spine, which can transmit various signals. If there is no spine, carp can not complete a variety of complex life activities.
Teeth are one of the important structures of fish, and their role is very important. Carp also have teeth. It is easier to see the teeth of carp if you can see them eating at close range. However, if they are not eating, it is not easy to observe the teeth, so some people will mistakenly believe that carp is toothless. To be exact, the teeth of carp are throat teeth, which are different from those of many animals, because their teeth are in their throat. On the whole, carp teeth are more like a comb, and each tooth is like a comb tooth.
Teeth play an important role in the life activities of carp, the most important of which is when they eat. When carp eat food, they bite it off with their teeth, chew it and then swallow it. In addition, when carp prey on some small aquatic animals, teeth can also play a very important role. It can be seen that teeth are indispensable for carp.
