Turtles and tortoises are fascinating creatures, and their shells play an important role in their survival. Turtles and tortoises need their shells not only for protection, but also for other biological processes such as pH buffering, storage of essential nutrients, and nerve endings. Turtles and tortoises cannot live without their shells, as they are connected to their shells through their nerves, skin, ribs, and spinal cord. If a turtle or tortoise cracks its shell, it can take several months for it to heal. It is important for owners to monitor their turtles’ shells for any damage or cracks, and to seek medical attention if necessary.
