Komodo dragons are the largest living lizards in the world. They are identified by their massive size, flat heads, bowed legs and long, thick tails. A Komodo dragon can live as long as thirty years. They have tough skin reinforced with osteoderms or bony plates, and they can come in a variety of colours, including gray, green, blue, and orange.
Komodo dragons are generally solitary outside of the mating season. Males maintain and defend a territory and patrol up to 1.2 miles (2 kilometers) per day. Komodo dragons mate between May and August and females lay about 30 eggs each in September.
