Shark is a very fierce fish, just look at their sharp teeth, you can also feel their ferocity. The role of shark teeth is very large, mainly the following two:
1, predation: In the process of shark predation, the role of teeth is indispensable. Their sharp teeth can cause severe damage to their prey, and the bleeding area of the wound will be larger, so the prey will bleed to death very quickly. After the prey loses strength or even dies due to blood loss, sharks can enjoy their food.
2. Feeding: The function of teeth is not only reflected in the process of predation, but also in the process of feeding. Some prey are so large that sharks can't swallow a bite, so they need teeth to break and grind their food, which is the role of teeth in feeding.
Shark teeth are different from other animals, because their teeth can grow back after they fall out. The number of teeth they replace in their lifetime can reach tens of thousands, and other animals, including humans, can not replace their teeth so frequently. Most sharks have several rows of teeth in their mouths at the same time, usually two to four rows. The teeth in the front row are the teeth that the shark is currently using, and when there is a problem with this row of teeth, the teeth in the back row will be replaced immediately. Some sharks have whole rows of teeth that grow out and fall out, allowing them to have a row of teeth that they can use all the time and not delay their hunting.
