Great White Sharks are stealthy hunters and the secret is in their skin. They have skin that is covered by tiny flat V-shaped scales. These scales are not like other fish scales. The shark’s scales, called dermal denticles, are actually closely related to teeth. These denticles decrease drag and turbulence allowing the shark to swim faster and more quietly. Olympian swimsuit designers have taken a page from the shark’s playbook and created a fabric that mimics the exact proportion of the shark’s denticles, hugely improving a swimmer’s speed. More about the great white shark can be found in our Great White Shark featured story.
