Home to the famous Komodo Dragon, these lizards are also known as the Komodo Monitor. They can grow up to 10-12 feet in length and can weight some 150-250 pounds. Fossils very similar to the Komodoensis have been found in Australia dating back greater than 3.8 million years ago and its body has remained pretty much unchanged. These creatures can live for between 30-40 years. They were thought to be deaf, however they do hear, albeit poorly. However, their sense of smell is particularly acute. They are able to detect carrion from as far away as 2.5-6.0 miles. This is their mainstay as far as diet.
