You pause from hiking down the mountain to enjoy the sunset. Below lies a serene tropical beach and above a cloud forest. Around you are hills covered with savanna. In the ravines between the hills are monsoon forests. An amazing range of environments, you think to yourself, for an island only twenty miles long and ten miles wide.
Venom or Toxic Bacteria?
For years scientists thought that the Komodo Dragon did not poison its victims, but that its fearsome bite infected the animal with septic bacteria that slowly weakened and killed it. A recent study by led by Dr. Bryan Fry from the University of Melbourne, however, showed that the Dragon does have venomous glands in its mouth. The venom keeps the victim's blood from clotting at the wound leading to a drop in blood pressure. The loss of blood and the lower the blood pressure weaken the animal and cause it to eventually stop moving so the Dragon can safely approach and finish it. Fry believes that this specialized bite and venom shortens the contact the Dragon has with its victim allowing it to take much larger prey than might otherwise be expected.
