The Komodo is well known to be the largest lizards found on the earth. They are not only the largest but also the heaviest lizards as well. They were introduced by the people living in the islands of Indonesia. They are native to the island and can easily sprint at the speed of 13 to 15 miles per hour. They can spend hours at one spot waiting for their prey to come. Some researchers have declared that these species are the closest one to dinosaurs. The Komodo dragons are said to have been thriving on the earth since millions of years. They have more than 3000 species found on islands. These reptiles also range in color, from yellow-gray to brown depending on the location they are living in. Their rough skin protects the huge dragon from injuries and bites of other animals. The muscular tail and powerful claws make them ever more deadly.
