The animals of the world may increasingly need our help with big issues like preserving habitat or species conservation. But sometimes individual animals need our help as well. Left disabled without fins, flippers, beaks or tails because of disease, accidents or even human cruelty, these unfortunate creatures need what amounts to a miracle if they are to survive. Luckily for them, sometimes miracles do happen. Amazing prosthetics made possible by the latest engineering and technology are able to provide just what they need. And scientists are finding that innovations created in the process are benefitting both animals and humans.
