As the important weapon of shark, teeth grow on whole shark’s body. Is it true?

Then my answer is yes. But how comes? Yap, as I’ve ever watched on documentary movie, teeth is very important tool for shark to keep alive. As important as its tooth, each of shark’s body parts is meaningful to give it a power. For this part, I want to tell you if teeth grow well on whole shark’s body. Teeth are modified as skin for shark called Dermal dentacles. Dermal dentacless is used for reducing turbulence when shark swims through deep water or seeks their prey just like sea lion. If it’s stroked from front side to back side, it’ll be felt something slippery. But it’ll be felt rough as we do the opposite. Dermal dantacless is looked extremely the same shape as the actual teeth.
