Komodo Dragon

The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a species of lizard found in the Indonesian islands of Komodo, Rinca, Flores, Gili Motang, and Padar. A member of the monitor lizard family Varanidae, it is the largest living species of lizard, growing to a maximum length of 3 metres (10 ft) in rare cases and weighing up to approximately 70 kilograms (150 lb).
Their unusually large size has been attributed to island gigantism, since no other carnivorous animals fill the nicheon the islands where they live.
