The Komodo Dragon is not only the largest lizard in the world, but it also one of the most aggressive and is so powerful That it is Able to take prey many times it's own size. However, Komodo Dragons are also in severe danger in their natural environments as hunting and habitat loss, along with a Shortage of prey, has led to population declines on the few islands where They are found in the Komodo National Park, meaning That They are now Listed on the IUCN's Red List and therefore have some legal protection.

Komodo Dragon Anatomy and Appearance
The Komodo Dragon is an enormous reptile That can grow up to three meters long and weigh 150kg. They are incredibly strong and powerful with long, thick bodies, short, muscular legs and an almighty That tail is used for both fighting and for propping up the animal when it is standing on it's Hind legs.

By flicking it's tongue out of it's mouth, the Komodo Dragon is Able to "taste" scent particles in the water to locate both live and dead prey up to 8km away.

 
Distribution and Habitat Komodo Dragon
Although the Komodo Dragon would have once been widespread across many Indonesian islands, They are today confined to just five the which all lie in the Komodo National Park. The islands of Komodo, Rintja, Gillimontang, Padar and the western tip of Flores are the last remaining homes for these enormous animals are most commonly found That in open dry savannah woodlands along with scrubby hillsides and on, and can also be found inhabiting dried- up river beds. It is thought That Komodo Dragons evolved to be so big on these islands due to the presence of a large number of Mammalian species have since gone extinct That. Today however, They are Becoming more in their natural environments Threatened with the loss of habitats to deforestation for Their timber has pushed the last remaining Populations into smaller and more isolated regions.

Komodo Dragon Behaviour and Lifestyle

The Komodo Dragon is a solitary and powerful predator roams a territory That the which is dependent on the individual's size, with the average adult covering a distance of around 2km every day. They are also known to be excellent swimmers, traveling from one island to another over a Relatively long distance.They are solitary animals Although, a number of Komodo Dragons will gather around a single Often kill with smaller individuals normally having to give way to the larger ones. In order to catch Such large animals, Komodo Dragons can sit for hours hidden in the vegetation and are well camouflaged by Their gray-brown skin as They sit waiting for a prey animal to pass by. The Komodo Dragon then ambushes it's victim with incredible speed and force.

The young hatch after an incubation period That Lasts for Between 8 and 9 months and are boldly marked with cream bands (which They lose as They get older), and are completely independent from when They leave Their shell. However, until They grow to a larger size, young Komodo Dragons will venture up into the trees where They Will spend most of Their time until They are big enough to look after Themselves on the ground. Komodo Dragons growing niche to live for an average of 30 years in the wild.

The teeth of the Komodo Dragon are sharp and serrated but That They mean this animal can not chew. They instead tear bits off the carcass and throw it backwards into their mouths, Able to swallow it whole aided by Their neck muscles flexible.

 
Komodo Dragon Predators and Threats
Due to the fact That the Komodo Dragon is the most dominant predator in it's environment, mature adults have no natural predators in their native habitats. The smaller and more vulnerable young however, seem to have adapted to spending Their initial days in the trees to avoid being eaten by larger Komodo Dragons.Since the arrival of people on these islands though, Things have changed Dramatically with Humans having hunted the Komodo Dragons and Their encroaching on native habitats with Their growing settlements and forest clearance for both timber and agriculture. Komodo Dragons are also Threatened by volcanic activity on these islands geologically active the which can cause declines in their prey species, in turn affecting the local Komodo Dragon Populations.

Komodo Dragon Interesting Facts and Features

The Komodo Dragon is known to have fifty different types of toxic bacteria in their saliva That Thrive on traces of flesh, bite-Causing Wounds to Quickly Become infected. Recent research however, indicates That the real reason for the high success rate Such a poisoning in it's prey Could be down to the fact That the Komodo Dragon may have a venom gland in it's mouth. Although Komodo Dragons have thrived in this part of the Indonesian archipelago for Millions of years, They were not known to the world until around a century ago when reports CAME in from a pilot swam to Komodo Island That after his plane went down. The Immense size of the Komodo Dragon is thought to come from the fact That They would have once hunted large Mammals That would have then existed in Indonesia, Including a species of Pygmy Elephant the which is now thought to have been extinct for Thousands of years. This means That the main prey of the Komodo Dragon today, has all been introduced to the islands by Human settlers.

Today, the Komodo Dragon is listed by the IUCN as a species That Is Vulnerable in it's natural environment and therefore Potentially faces extinction in the near future. Although once widespread on Indonesian islands Numerous That They are now confined to just a few with Between 3.000 and 5.000 individuals thought to be left roaming the rich, volcanic forests. Increasing interest in them from the tourist industry has Meant That though local people have more reason to try and protect them and the handful of habitats where They still survive.
