Sharks are very fierce fish, and sharp teeth can be said to be a symbol of their fierce character. The role of teeth is very important, whether it is predation, or eating, can not be separated from the help of teeth. The number of teeth in sharks is also very large, some sharks have thousands of teeth in their mouths, sometimes up to 6000. Moreover, sharks can replace their teeth many times, and the number of teeth they replace may reach tens of thousands in their lifetime, sometimes thousands in a year. This situation is basically impossible for other animals.
As mentioned above, the number of shark teeth is very large. In addition, sharks have not only one row of teeth, but many rows. Generally speaking, there will be 2-4 rows of teeth in the mouth of sharks at the same time, but not necessarily, the number of rows of teeth will vary from shark to shark. The number of teeth in each row may be about 1600, which is also one of the reasons for the large number of teeth in each row.
In addition, the tooth structure of sharks is very strange. For example, in the mouth of a great white shark, there are rows of sharp teeth, and the front row of teeth is the one they currently use. After this row of teeth falls off, the teeth in the back row will be filled immediately, replacing the teeth in the front row, so it will not affect the use. In addition, some sharks have teeth that grow in regularly and fall out regularly. Because they have many rows of teeth, even if sharks keep changing their teeth, it will not affect their use.
