Named after the island where humans spotted a dragon-like creature for the first time, the Komodo dragon is an endemic Indonesian species found on Komodo Island and its neighboring islands. Famous for stunning sceneries and calm winds, it is the perfect atmosphere for trekking and for your up-close encounters with these prehistoric Komodo dragons. Even more so, in recent years, visitors have increasingly swamped this Indonesian island, intimidated by the thrill of coming so close to such a wild and endangered creature. Komodo dragons are not to be taken lightly, as they are one of the strongest predators in the lizard species, having taken on much bigger prey, even humans. Their sense of smell is highly developed, and is their greatest asset when hunting for prey. Using their forked tongues, the dragons have an acute sense of smell that they can detect warm-blooded animals from up to five miles away. These giant lizards can reach up to 10 feet in length! Male dragons can grow up to 10 feet or three meters long , while females can grow up to eight feet or two and a half meters long. They have a muscular tail that is almost as long as the length of their bodies. Some of them weigh a whopping kg pounds , with the average weight of the Komodo dragon being about 80 kg pounds.

Volcanic activity, earthquakes, loss of habitat, fire, [27] [13] tourism, loss of prey due to poachingand illegal poaching of the dragons themselves have all contributed to the vulnerable status of komodo dragons diet Komodo dragon. Biology Letters. San Diego Tribune.

Komodo dragons are large lizards with long tails, strong and agile necks, and sturdy limbs. Their tongues are yellow and forked. Adults are an almost-uniform stone color with distinct, large scales, while juveniles may display a more vibrant color and pattern. The muscles of the Komodo's jaws and throat allow it to swallow huge chunks of meat with astonishing rapidity. Several movable joints, such as the intramandibular hinge opens the lower jaw unusually wide. The stomach expands easily, enabling an adult to consume up to 80 percent of its own body weight in a single meal, which most likely explains some exaggerated claims for immense weights in captured individuals. When threatened, Komodos can throw up the contents of their stomachs to lessen their weight in order to flee.

Although males tend to grow larger and bulkier than females, no obvious morphological differences mark the sexes.

The Dutch colonial government instituted protection plans as early as Bibcode : SciNa. Archived from the original on 8 October Pregnant females then lay about 30 eggs, which they bury in the earth until they hatch eight months later. But they are known to be very effective hunters too. The first two live Komodo dragons to arrive in Europe were exhibited in the Reptile House at London Zoo when it opened in Males also sometimes wrestle one another to earn mating rights. A large animal may take days to succumb to an attack, but the dragons will be there to consume when the time is right. Both hatchlings were males. Although there are anecdotes of unprovoked Komodo dragons attacking or preying on humans, most of these reports are either not reputable or have subsequently been interpreted as defensive bites. An average of 22 eggs are laid and buried. Archived from the original on 30 October Our Bird House team is celebrating the arrival of a ruddy quail dove squab—the first of its species to hatch at the Zoo! While the eggs incubate in the nest for about nine months, the female may lay on the nest to protect the eggs.

Reaching up to 10 feet in length and more than pounds, Komodo dragons are the heaviest lizards on Earth. They have long, flat heads with rounded snouts, scaly skin, bowed legs, and huge, muscular tails. Komodo dragons have thrived in the harsh climate of Indonesia's Lesser Sunda Islands for millions of years.

Social Structure Because large Komodos cannibalize young ones, the young often roll in fecal material, thereby assuming a scent that the large dragons are programmed to avoid. They have been known to bring down horses and water buffalo. They will also commonly eat invertebrates , wild boar , goats , water buffalo and other large prey that are unlucky enough to stumble into their ambush site. The poison lowers blood pressure and impairs coagulation, leading to blood loss and shock. Eggs receiving a Z chromosome become ZZ male ; those receiving a W chromosome become WW and fail to develop, [69] [70] meaning that only males are produced by parthenogenesis in this species. They rely heavily on their sense of smell, using their forked tongues to sample the air. Delays in egg laying may occur, which could help the clutch avoid the brutally hot months of the dry season. Villagers sometimes poison carrion bait to reduce the population, much like ranchers of the American West poison sheep carcasses to rid the area of coyotes and mountain lions. Populations remained relatively stable on the bigger islands Komodo and Rinca , but decreased on smaller islands, such as Nusa Kode and Gili Motang, likely due to diminishing prey availability. At about 8 months old, the dragons become too big to live in trees and start living on the ground.
