Sharkskin actually increases drag American Institute of Physics

Webb4 juni 2024 · Most modern sharks have linear denticles , which may improve swimming efficiency over long-distance migrations. By contrast, the extant geometric denticles are found mostly on small, sit-and-wait ambush predators that live in the deep sea, including the cookiecutter shark ( Isistius brasiliensis ) and the lantern shark ( Etmopterus perryi ) … Webb9 feb. 2012 · “In life, sharks are very flexible.

But we don’t know what that balance may be. Webb15 maj 2014 · Compared with a smooth control model without denticles, the 3D printed shark skin showed increased swimming speed with reduced energy consumption under certain motion programs.
