Identification

This large, herbivorous lizard is one of the most common pet reptiles. It starts out bright green and can be a variety of colors in adulthood. It is distinguished by a row of spiked scales down its spine which grow quite long on adults, large jowls adorned with hard circular scales, a long dewlap, and its impressive muscular body with a thick tail that often has black bands. They often reach 5 feet in total length, but can exceed 6 feet. Large adults can weigh over 20 lbs.
