These pointed scales are also known as dermal teeth. They give the shark's skin the feel of sandpaper. The scales disrupt turbulence over the skin, considerably reducing the drag on the shark as it swims. The reduction in fluid drag allows the shark to swim with less energy. This unique design is duplicated in swimsuits and other surfaces that move through the water. The scale bar is 100 um and the magnification is 129x.
