King of the lizards: 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 species of reptile with ancestors that date back more than 100 million years. Komodo dragons were unknown by western scientists until 1912, and their common name came from rumors of a large dragon-like lizard occurring in the Lesser Sunda Islands. Indeed the yellow color of the Komodo dragon’s long, forked tongue reminds people of mythical dragons that spit fire!

These large lizards range in color from black to yellow-gray, depending on their location, and have a rough, durable skin reinforced with osteoderms (bony plates) protecting them from injuries from scratches and bites. Komodo dragons also have a large, muscular tail and long, powerful claws.

HABITAT AND DIET

Komodo dragons live on only five islands in southeastern Indonesia: Indonesia’s four islands within Komodo National Park (Komodo, Rinca, Gili Montang, Gili Dasami), and the island of Flores. The islands are volcanic in origin, rugged and hilly, and covered with both forest and savanna grassland. Komodo dragons have the smallest home range of any large predator in the world! They like it hot, with daytime temperatures during the dry season that often reach 95 degrees Fahrenheit (35 degrees Celsius) with 70-percent humidity.  

Some dragons scratch shallow burrows to rest in at night to keep warm and as a cool shelter to retreat to from the heat of the day. They may either make their own burrows or use an existing one another lizard created.  Sometimes these burrows can be seen along the slopes of dry streambeds among tree roots. However, not all Komodo dragons use burrows; in fact, one adult male on Komodo Island often sleeps at night in an abandoned hut that visitors used to stay in!

An adult dragon leads a life of leisure. It emerges from its burrow to look for a sunny spot to warm up in. Then it’s off to find breakfast, followed by a nice long nap in the shade during the hottest part of the day. After a late afternoon meal, the dragon is ready for bed, sleeping soundly in its burrow until a new day begins. It is a solitary creature that lives and hunts alone.

An adult Komodo dragon eats whatever food is available. Its natural prey, however, is the Timor deer. The deer are wary and quite agile, requiring the dragon to resort to lying in ambush in the long grass next to game trails, in order to be successful in hunting. When the deer passes by, the dragon uses its long claws and sharp teeth to attack. If the prey escapes, the dragon can rely on its long tongue to find its whereabouts, even up to a mile away (1.6 kilometers) away!

Komodo dragons also eat water buffalo and wild pigs, both of which were introduced by man, as well as snakes and fish that wash up on the shore. On Rinca and Komodo islands, pigs have become common in some areas and are now competitors for food with the big lizards. Some dragons have visible scars from conflicts with wild boars. Komodo dragons may also be cannibalistic. Fortunately, the young spend their lives in trees, which likely helps reduce their risk of predation from the adults.

In addition, Komodo dragon saliva contains potentially harmful bacteria that are thought to help weaken prey that are too large for a single dragon to overpower. One study discovered 23 species of bacteria in the saliva of wild dragons, yet only 10 species of bacteria in the saliva of dragons in zoos. Some recent research suggests that Komodo dragons might also be venomous due to some of the properties of components in their saliva. Whether they are venomous or not is subject to interpretation at this time; it is too early to make this conclusion until more research is done.
