KOMODO DRAGON: The Komodo dragon is the largest and deadliest lizard in the world. This dinosaur-like predator can grow up to 10 feet in length and weigh close to 200 pounds. Male dragons fight like sumo wrestlers, rising up on their hind limbs and tail and using their weight to knock the other off balance. These encounters often end in injury or death. Its forked tongue can detect chemical trails given off by animals. It will wait in ambush, then strike its prey with its giant tail, knocking the animal to the ground. Next, the dragon delivers a nasty bite. The bacteria in its saliva slowly poisons the animal over the course of several days. The dragon follows its victim at a leisurely pace, then begins to feed when the animal can no longer defend itself. It can eat up to 80 percent of its body weight in a single meal.
