Their teeth are very unique and can grow back after falling off.

They can change tens of thousands of teeth in their lifetime.

Sometimes they have to change thousands of teeth a year.

Generally speaking, sharks have several rows of teeth in their mouths at the same time. When there is a problem with the front teeth, the back teeth will be filled immediately, so their use will not be delayed.

1. What is the function of shark teeth? Sharks are very fierce fish. Just look at their sharp teeth and you can feel their ferocity.

Shark teeth play a very important role, mainly including the following two aspects: 1. Predation: In the process of shark predation, teeth play an indispensable role.

Their sharp teeth can seriously hurt their prey, and the bleeding area of the wound will be larger, so the prey will bleed to death quickly.

Sharks can enjoy their food after their prey loses strength or even dies because of blood loss.

2, eating: the role of teeth is not only reflected in the process of predation, but also reflected in the process of eating.

Some prey are so big that sharks can't swallow a bite, so they need teeth to crush food. This is the role of teeth in eating.

Second, will the shark's teeth grow if they fall off? Sharks' teeth are different from other animals because they can grow back after falling off.

They can change their teeth by tens of thousands in their lifetime, and it is impossible for other animals, including humans, to change their teeth so frequently.

Most sharks have several rows of teeth in their mouths at the same time, usually two or four rows.

The teeth in the front row are the teeth that sharks are currently using. When there is a problem with this row of teeth, the teeth in the back row will be filled immediately.

Some sharks' teeth are arranged in rows and fall off in rows, so that they can always have a row of teeth to use without delaying their prey.
