Turtles are characterized by a very strong shell. When attacked, turtles can retract their heads, tails and limbs into their shells (except turtles and snapping turtles). Most sea turtles are carnivores, feeding on worms, snails, shrimp and small fish, as well as stems and leaves of plants. Turtles are distributed almost everywhere in China, but the yield in the middle and lower reaches of the Yangtze River is higher.
