In the life course of animals, teeth play a vital role. In order to adapt to changes in their own survival and living conditions, the morphological structure and functional characteristics of animal teeth are constantly changing. Different types of animals have formed tooth structures that are suitable for their own feeding habits.
For carnivores, teeth are the most important part. The harder and sharper the teeth, the stronger the predatory ability and the higher the status. So do you know which animal has the hardest teeth in the world?
Speaking of the animals with the hardest teeth in the world, many people will think of lions, tigers, crocodiles, hyenas , Tibetan mastiffs, bears, wolves, etc., but this is not the case. The animal with the strongest teeth in the world is probably a shark.
The teeth of lions, tigers, crocodiles, hyenas, Tibetan mastiffs, bears, wolves, etc. are all extremely sharp and hard. There is no doubt about this, but the teeth of sharks are many times harder than them!
Shark teeth have 5-6 rows. Not only that, their tips face backward and are barb-shaped. There is a high cusp in the middle of the tooth and a low cusp on each side.
Except for the outermost row of teeth, which function as teeth, the remaining rows are spare teeth. Once the outermost tooth is lost, the inner row of teeth will immediately move forward to fill the gap that replaced the lost tooth. It is this magical function that allows sharks to become the animals with the strongest teeth in the world.
Sharks have strong hunting abilities and often break their teeth in the process. Therefore, sharks will constantly replace their teeth as they grow. Each shark will replace more than 20,000 teeth in its lifetime. It is this constant replacement that ensures the hardness of shark teeth.
As the animal with the hardest teeth in the world, shark teeth are not only hard, but also have extremely strong biting power, with a bite pressure of up to 18 tons.
