Sharks
Riblet Drag-Reducing Ship Coatings
Run your hand from a shark's head toward its tail and the skin feels smooth. Run it the other way and it feels like sandpaper. Shark skin is covered in thousands of tiny, tooth-like scales called dermal denticles. Each denticle has a flattened crown, often with fine ridges running from front to back, aligned with the direction of swimming.
