Why a Speeding Shark is Like a Golf Ball


Why a Speeding Shark is Like a Golf Ball: "Shortfin mako sharks can shoot through the ocean at up to 50 miles per hour (80 kilometres an hour). Now a trick that helps them to reach such speeds has been discovered – the sharks can raise their scales to create tiny wells across the surface of their skin, reducing drag like the dimples on a golf ball."
