Chinese Alligator

Alligator sinensis

A small, critically endangered alligator from China's Yangtze River that digs long underground tunnels.

About the Chinese Alligator

Chinese alligators usually grow to about 5 feet long, about half the size of the biggest American alligators, and most weigh less than 50 pounds. They have sturdy heads and slightly upturned snouts. They are the only alligators outside the Americas and live in slow fresh waters of the lower Yangtze River. Their blunt teeth crush snails, crabs and other shelled animals, and they also eat insects, fish, young ducks and rodents.[1]
