Although not great swimmers, they are capable of floating and can be carried by ocean currents. In one remarkable case, an adult tortoise came ashore on the east coast of Africa after being carried from its island home in the Indian Ocean. Based on the amount of barnacle growth on its shell, it was determined to have been out at sea for several months.
