1. The Chinese & American Alligator
By Heather Shand

2. What is the Chinese Alligator?
The Chinese alligator is one of two species of alligator. The other is the American alligator. The Chinese Alligator grows to about 6 ft., though at one time it was longer and it can live to be at least 70 years old. It hunts mainly at night, feeding on hard-shelled mollusks, but also fish and occasional birds and rats. Sometimes it eats domestic ducks, which angers many farmers. During the winter, it hibernates for about six months in a complex burrow system. Historically, these alligators were widespread in slow-moving rivers, streams, lakes, ponds, and so on in areas around the lower Yangtze River.

5. What is the American Alligator?
The American alligator (Alligator mississippiensi) is the largest reptile in North America. It has a large, dark (usually black), slightly rounded body and thick limbs. American alligators mainly eat fish, turtles, various mammals, birds and other reptiles. Males can grow up to 18 feet; females are smaller. Alligators live in freshwater environments, such as ponds, marshes, wetlands, rivers, and swamps, as well as brackish environments.
