Do fish scales reduce drag
WebIn the real world, the use of dimples has seemingly been restricted to the outer surface of golf balls almost exclusively. In golf ball manufacture, dimples have been accepted practice since the 1930s, when research showed how they could increase lift and reduce drag of a spherical object in flight. WebGanoid scales are diamond-shaped, shiny, and hard.Most bony fishes have cycloid or ctenoid scales. Both cycloid and ctenoid scales consist of an outer layer of calcium and an inner layer of connective tissue. Cycloid scales overlap from head to tail, an arrangement that helps reduce drag as a fish swims. Cycloid scales are circular and smooth.
