The evolution of the shark is full of gaps and theories, due to the animal's cartilaginous skeleton, which unfortunately means that few fossils remain thousands of fossilised shark scales have been found, along with numerous fin spines. Over many millions of years of evolution, sharks have become some of the speediest swimmers in the ocean thanks to several adaptations the first is their unique skin, which is made up of millions of small v-shaped placoid scales, also called dermal denticles.
