Key insights

  • 1

    Role of Denticles: The study highlights that the denticles on the shark's skin are essential for drag reduction. These structures help in creating microturbulence, which reduces the friction between the shark's body and the water.

  • 2

    Adaptation to Speed: It was found that the shark can adjust the angle of its denticles depending on the speed at which it is swimming. This dynamic adjustment allows for optimal drag reduction across a range of speeds.

    Implications for Human Technology: The research could have significant implications for human technology, particularly in the design of more efficient underwater vehicles and swimsuits that mimic the drag-reducing properties of shark skin.
