A komodo dragon roaming on Rinca Island, part of the protected area of Komodo National Park. They don’t breathe fire but the largest lizards in the world can kill a buffalo or any one of the intrepid tourists who flock to their deserted island habitats. Three metres long and weighing up to 70 kilograms, Komodo dragons are lethargic, lumbering creatures but they have a fearsome reputation for devouring anything they can, including their own.
