Shark Skin Inspires Several Human Innovations

Dermal denticles are an extremely effective adaptation that provide so many benefits to sharks.

Dermal denticles give a thicker layer of protection to sharks, making it harder for predators to bite through their skin.  Additionally, the shape of the denticles will deter microorganisms from latching on to and building up on a shark's skin. Dermal denticles are so unique that they have inspired a lot of biomimicry from swimsuit designs to making boats faster. Shark skin was even used as sandpaper way before the manufactured kind we use today.

So who's ready to evolve to have teeth skin so we can live in the ocean?
