The shell of a turtle is more than just a cover, it’s a vital part of the animal’s skeleton that protects its organs. And although pet turtles are usually safe from the dangers that might crack it, wild ones aren’t so lucky. Fires, and especially cars often damage them, causing serious consequences. However, not every injury they inflict is fatal. With proper care, cracked turtle shells can be fixed, and one wildlife organization has come up with a genius way to do so. Recently, Wildthunder Wildlife & Animal Rehabilitation & Sanctuary took to Facebook, asking for discarded bra fasteners: “We use them to mend our turtle shells!” they wrote.
