Turtles spend most of their lives in water. They are adapted for aquatic life, with webbed feet or flippers and a streamlined body. Sea turtles rarely leave the ocean, except to lay eggs in the sand. Freshwater turtles live in ponds and lakes, and they climb out of the water onto logs or rocks to bask in the warm sun. Tortoises are land animals. Their feet are round and stumpy, adapted for walking on land. They also dig burrows with their strong forelimbs, and slip underground when the sun gets too hot. Terrapins live on land and in water, usually in swamps, ponds, lakes and rivers.
