There are over 3,000 lizard species, but the Komodo dragon wins the prize for being the largest living lizard in the world! It is a type of monitor lizard, an ancient reptile species with ancestors that date back more than 100 million years. This awesome creature can grow up to 10 feet (3 meters) long and weigh up to 176 pounds (80 kilograms). A very handsome adult male, named Sunny, lives in a specially designed enclosure just outside of our Reptile House. He has indoor and outdoor access, a heated waterbed platform, and gas heaters for warmth, as well as opportunities for his keepers to provide enrichment for him. Sunny is a curious, intelligent, and mild-mannered dragon who comes when his keepers call him. Be sure to check out our juvenile dragons inside the Reptile House. They have the bright colors typical of young Komodo dragons.
