What happens when a young elephant steps on a buried land mine? What happens when a sea turtle's flipper is injured by a predator? Thanks to recent advances in technology, we have new ways to design and build prosthetic body parts that can help these animals thrive. Meet an Asian elephant named Mosha, a Kemp's ridley sea turtle named Lola, a German Shepherd named Cassidy, a greylag goose named Vitória, and Pirate, a Berkshire-Tamworth pig. Each of these animals was struggling, but through a variety of techniques and technologies, humans created devices that enabled the animals to live and move more comfortably. Discover the stories of how veterinarians, doctors, and even students from around the world used 3D printing and other techniques to build bionic body parts for these amazing animals.
