>>AeroSHARK replicates this hydrodynamic property on aircraft. It is a "special film" made up of "tiny 50-micrometre riblets that reduce aerodynamic drag during flight." While it's at this point obviously tested and proven to work, I wonder about the size of that texture in relation to the texture on actual shark-skin, and whether they are working at similar Reynolds numbers.
