SHARKS!!! SHARKS!!! SHARKS!!!
Sharks are so highly adapted for swimming and hunting that they have very specialized skin made up of microscopic teeth called "Dermal Denticles" meaning skin teeth. These 'teeth' are designed to reduce drag by up to 8% pointing back towards the tail (similar to dimples on a golfball). They also reduce turbulence which makes sharks undetectable by microphones or other fish when cutting through the water.
