The Komodo dragon (Varanus komodoensis) is a large species of lizard found in the Indonesian islands of Komodo, Rinca, Flores, and Gili Motang. It is a reptile. In the wild, an adult Komodo dragon usually weight around 70 kilograms and average length of 2-3 meters. The largest verified wild specimen was 3.13 meters long and weight 166 kilograms, including undigested food.
The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced serrated teeth that can measure up to 2.5 cm (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. This creates an ideal culture for the virulent bacteria that live in its mouth. It also has a long, yellow, deeply forked tongue. The Komodo dragon does not have a particularly acute sense of hearing, despite its visible earholes, and is only able to hear sounds between 400 and 2000 hertz. The Komodo dragon uses its tongue to detect, taste, and smell stimuli.
Komodo dragons are carnivores. Although they eat mostly carrion. Komodo dragons have also been observed knocking down large pigs and deer with their strong tail. Komodo dragons eat by tearing large chunks of flesh and swallowing them whole while holding the carcass down with their forelegs. For smaller prey up to the size of a goat, their loosely articulated jaws, flexible skull, and expandable stomach allow it to swallow its prey whole. The Komodo dragon diet is wide-ranging, and includes invertebrates, other reptiles (including smaller Komodo dragons), birds, bird eggs, small mammals, monkeys, wild boar, goats, deer, horses, and water buffalo. Young Komodo will eat insects, eggs, geckos, and small mammals.
