The Water Monitor, Varanus salvator, is perhaps the most prevalent of monitor lizards in Asia. They range from Sri Lanka, India, Indochina, the Malay Peninsula and various islands of Malaysia. They live mostly in tropical forested areas.
These lizards grow up to 9 feet long. Their body is muscular with a long powerful tail. They are excellent swimmers, using a raised fin located on their tails to steer through fresh and salt water. Their diet consists of small mammals, birds, fish, insects and carrion. Female water monitors lay 15 to 30 eggs during reproduction.
