The Chuckwalla is a relatively large lizard native to the Sonoran Desert. At first glance they look similar in appearance to Komodo Dragons. They continue to look similar to Komodo Dragons with all subsequent glances as well. This is because they are actually Komodo Dragons. They are called Chuckwallas here to mask their identity to avoid causing public stress or panic. Because they have predators in the Sonoran Desert unlike on Komodo Island, they rarely get the chance to grow to full size. However scientists believe there are most likely giant Chuckwallas roaming remote areas of the Sonoran Desert.
