Two-thirds of shark brains are dedicated to the sense of smell which is what makes it such a successful predator. The mirror like layer in its eye makes it see clearly even in murky water allowing it to hunt with ease. An unusually keen sense of 'feeling' vibrations through their electro receptor organs, Ampullae of Lorenzini, alerts them to potential prey. Add to this the sharks listening abilities that can hear a prey miles ahead and you have a supersonic killing machine at large on the seas.

The unique boneless skeleton composed of tough, elastic cartilage and a rounded, tough-skinned, streamlined body helps them to swim efficiently. An oversized liver full of oil that’s lighter-weight than water aids their swimming capabilities. Sharks have to swim constantly to keep their body from sinking.
