Kemp’s ripley sea turtles are the rarest sea turtle species in the world. Their flippers are often injured by sharks, boats, or fishing gear. Some turtles even lose their flippers completely. The injured turtles often cannot swim. They do not survive in the wild. However, three engineering students from Worcester Polytechnic Institute had an idea. They designed a prosthetic flipper for a turtle named Lola. The students attached the prosthetic to the stump of Lola’s amputated right flipper. Soon she could swim easily. The prosthetic imitates the way sea turtles’ flippers naturally work. The students hope their design can be used to help other sea turtles, too.
