OTHER MONITOR LIZARDSThere are dozens of species of monitor lizards found in Africa, Asia, Indonesia, New Guinea, and Australia. Indian Monitors are thought to have been transported by natives to the Polynesian Islands, possibly as a food source. Monitors have a unique ability to greatly increase the size of the mouth cavity enabling them to swallow their prey whole. The Nile Monitor (right) is the largest lizard in Africa, sports a distinctive blue tongue and has been seen as long as 8 ft. It will lay eggs in termite mounds which provide a natural incubation! The Earless Monitor is a semi aquatic lizard that is native to Borneo. These lizards (along with some other reptiles) continue growing their entire life.
