How many teeth does a shark?

The shark is one of the most amazing animals, but the shark is one of the most dangerous predators of the water world. Sharks have a very interesting feature related to their teeth. And, specifically, a shark is a very quick change of teeth. Therefore, there are sharks that change teeth front row, on new on average once in two weeks!

How many teeth do sharks and how they are positioned? One day, to count how many teeth does a whale shark, the scientists caught it and pulled ashore. They were amazed by what they saw. In the mouth of the shark was about 14,000 small teeth that are shaped like igloos. But all of these teeth need to mouth the fish were delayed, and plankton, as whale sharks do not pose to humans no danger. But what about dangerous for people, white or tiger shark? How many teeth does a white shark? The teeth of these predators differ from a whale that have a triangular shape, unlike needle, and they are more wide and long. The white and tiger sharks around 280-300 sharp teeth. They are arranged in 5 rows, so many rows of teeth in sharks. The younger the shark, the faster the change of the teeth, as when hunting these predators often lose their precious teeth, leaving them in the victim. In order to reduce the risk of loss of their own teeth,nature has taught the sharks, after they grabbed the victim, to make movement from left to right (like a puppy, clinging to the pillow). So sharks never shake my head upwards so as not to lose their sharp teeth.

Such a frequent change of teeth in sharks is due to the fact that their food consists mainly of fish with a very dense and thick scales and other inhabitants of the water world that have enough solid body. So evolution has rewarded the sharks the best teeth and the most rapid change. On average, young sharks change the front row of teeth every three months, and their older relatives once in three months. At the moment sharks are one of the strongest and most dangerous predators in the seas and oceans.
