What do they use shark skin and shark teeth for?
scientists are studying shark skin to come up with a material to put on the bottom of boats so they don't get barnacles. Sharks never have barnacles on their skin. this is not because they swim fast but because there are tiny rides in their skin. Shark teeth as I've heard so far are used for nothing but necklaces and novelties. It doesn't hurt the shark though. Sharks have many rows of teeth, they lose them all the time. eventually after the teeth are lost they end up on shore where people can find them. I hope this helped! :)

What is difference between shark and human teeth?
Sharks have 5 or more rows of teeth. Humans only have 20 baby teeth and 32 adult teeth. Sharks can re-grow teeth. Humans only get 2 sets (milk teeth and permanent teeth). Sharks have serrated edges on their teeth. Shark teeth are not attached to the jaw. Humans bite and chew with their teeth. Sharks use their teeth to rip their prey apart.
