US military studying skin of world’s fastest shark to build faster aircraft

The skin of the mako shark is being studied by the US Army to help build faster aircraft, according to research presented on Monday. Makos, the world’s fastest sharks, have rows of millions of tiny raised scales along their sides and fins that researchers at the University of Alabama (UA) believe could be the reason for that lightning speed. Dr Amy Lang, a UA aeronautical engineer, is leading the research that she presented at a meeting of the American Physical Society Meeting on Monday, The Independent reported. The mako’s scales, called denticles, are translucent, flexible and shaped like tiny shark teeth.
