    Shark skin is made of a matrix of tiny, hard, tooth-like structures called dermal denticles or placoid scales. These structures are shaped like curved, grooved teeth and make the skin a very tough armor with a texture like sandpaper. They have the same structure as a tooth with an outer layer of enamel, dentine and a central pulp cavity.
    These scales also help the shark swim more quickly because their streamlined shapes helps decrease the friction of the water flowing along the shark's body, by channeling it through grooves.

    Do you know any coating/finishing for boats which has the same proprieties of shark skin?
    Do you think this kind of coating/finishing can improve the boat performance?

    Thanks in advance for you comments.
