1 . The discovery of the Komodo Dragons is one of the most important zoological (动物学的) surprises of the 20th century. Before 1912 it was completely unknown and it was believed that there were no more large lizards (蜥蜴) in the world. Then, in that year, a party of fishermen stopped at an almost completely-unknown small island in a group of islands. The fishermen brought back stories of a huge, prehistoric animal living there. The island’s name was Komodo. The largest of these lizards was over ten feet from nose to tail. Komodo dragons have also been discovered on several neighboring islands.
Are the dragons dangerous to humans? Yes. A Swiss tourist who sat down to have a rest while the other people of his tour group went ahead was attacked and eaten by a dragon. All that was left was a piece of his camera. A number of other people have been killed by dragon attacks over the years. The dragons can eat up to 80 percent of their own weight in a single meal. Their attack way is to wait behind trees, then rush forward and give a single large bite to the person or other animal. Most Komodo dragons prefer wild boar (野猪) or deer as their meals, but they will try to attack and get almost every other animal they can find, including other dragons. The largest dragons weigh around 150 kilos. Though the Komodo dragons can see well, they do most of their hunting based on smell. A dragon can recognize a certain smell from several miles when the wind is right. They will hunt when they have to, and these large lizards are more than happy to get an already dead animal when they come across one.
