Komodo Dragon

In the wild, an adult Komodo dragon usually weighs around 70 kilograms (154 lb), although captive specimens often weigh more. The largest verified wild specimen was 3.13 meters (10 ft 3 in) long and weighed 166 kilograms (365 lb), including undigested food. The Komodo dragon has a tail as long as their body, as well as about 60 frequently-replaced serrated teeth that can measure up to 2.5 centimeters (1 inch) in length. Its saliva is frequently blood-tinged, because its teeth are almost completely covered by gingival tissue that is naturally lacerated during feeding.[9] This creates an ideal culture for the virulent bacteria that live in its mouth. It also has a long, yellow, deeply-forked tongue.
