Newly hatched turtles must dig their way to the surface of the ground, obtain food, and protect themselves all on their own. Many animals prey on turtle eggs and newborn turtles. Various birds and mammals flock to beaches and eat baby sea turtles as they crawl toward the water. Fish attack many others as they enter the sea. Skunks, raccoons, and snakes dig up the nests of freshwater turtles and devour the eggs.
Scientists believe turtles live longer than any other backboned animal.
Some box turtles and tortoises have lived more than 100 years. Most of a turtle's growth occurs during the animal's first 5 to 10 years. The turtle continues to grow after reaching this age, but at a much slower rate. Turtles, like other cold-blooded animals, cannot remain active in cold weather. Species that live in regions with harsh winters must hibernate.
