Winter’s Tail: How One Little Dolphin Learned to Swim Again by Juliana Hatkoff, Isabella Hatkoff, and Craig Hatkoff

From chapters.ca:
When Winter, an Atlantic bottlenose dolphin, was just three months old, she was rescued from a crab trap off the east coast of Florida, her tail seriously damaged. She was rushed to Clearwater Marine Aquarium, where she was cared for by a special team around the clock. It wasn't clear that Winter would survive, but to everyone's amazement, she did. Eventually, though, Winter's tail fell off, which caused her to compensate by swimming with a side- to- side motion like a fish instead of an up- and down motion like a dolphin. Over time, it was apparent that she was seriously damaging her spine. Then something amazing happened. A team of experts from a renowned company that makes prosthetics for humans heard about Winter and decided to help. Now Winter is learning how to use a prosthetic tail, and her odds for living the normal life of a dolphin are looking great - Winter is thriving and using her new tail with great command.
