turtle (sh)




Any of more than 250 species (order Chelonia) of reptiles having a bony shell overlaid with horny shields; found in most parts of the world.

Turtles have existed for 200 million years, making them the oldest of all surviving reptiles. Most species are aquatic or semiaquatic; some are terrestrial. Turtles eat plants, animals, or both. They are toothless, have a horny beak, and range from less than 4 in. (10 cm) to more than 7 ft (2 m) long. They have sturdy, sprawling limbs with short feet or paddlelike flippers (marine turtles). Some species bend the neck sideways, but most pull the head and neck backward into the shell. Almost half the known turtle species are rare, threatened, or endangered.
