Shark skin is literally so cool!
Sharks have unique dermal denticles that feel rough to the touch (or so I’ve heard, I’ve never actually touched a shark). These tooth-like scales make sharks unique among fish species. They help sharks enhance their speed and reduce drag while also preventing algae or barnicles from settling on their skin.
Evolution truly is a beautiful thing! And sharks are also such beautiful creatures!
