Shark skin, known scientifically as dermal denticles, is a unique type of skin texture found on sharks. These tiny, tooth-like structures help reduce drag while swimming, allowing sharks to move more efficiently through water. The rough surface also provides protection against parasites and injuries. The structure of shark skin has inspired various applications in technology and design. For example, researchers have studied its properties to create materials that mimic its hydrodynamic features, which can improve the performance of swimwear and boat hulls. This innovative approach highlights the potential benefits of biomimicry in engineering and design.
