Just when scientists think they have discovered and recorded every species of insect that crawls the earth they find something new. Earlier this month, Peter Jager, the head of Frankfurt’s Senckenberg Research Institute reported the discovery of a unique eyeless spider. The creature that has a leg span (跨度) of six centimeters and a body size of just twelve millimeters was found in a cave inside the tiny nation of Laos, in Southeast Asia. It was identified as a member of the Huntsman spider, a large family that consists of 1100 species. However, the other members of the family all have eyes. The spider is the first one that has no eyes. They believe that the kind of spider has adapted to the fact that they do not really need the eyes to such a degree that they have dispensed with them altogether. But they are not the only creature to have done that. Over the years, scientists have discovered completely blind cave fish, and even a freshwater crab, which happens to live in the same cave as this eyeless spider! Surrounded by Burma and China on the northwest, Vietnam on the east, Cambodia on the south and Thailand on the west, the landlocked nation of Laos is filled with a large number of new and exotic (新奇的) species. In the last few years researchers have discovered the Saola—never-before-seen antelope-like creature, a small deer species called muntjacs, a tiny stripped rabbit and a rock rat that was thought to have been extinct 11 millions years ago. In addition to that it is also home to over one hundred species of large mammals ranging from tigers to macaques and over 165 species of amphibians (两栖动物) and reptiles like the terrible King cobra and the noisy Tokay gecko, a permanent resident inside most Laos households. 64. 小题1:Which of the following is the best title of passage?
