Biomimetics: the shark has inspired the creation of some innovative technologies. Its skin has been used as a model for creating antibacterial, hydro/aerodynamic and antifouling clothing; its fins have helped to improve the stability of airplanes thanks to “sharklets” and the shape of its tail has served as inspiration for tidal steam generators.
