　　Many people are frightened by spiders（蜘蛛）. They are especially afraid of large, hairy ones. The largest and most frightening of all spiders is the bird-eating spider, which lives in the hot, thick rain forests of northern South America.
　　Bird-eating spiders are a type of tarantula （狼蛛）. They are very hairy. Some of these giant spiders can spread eighteen centimeters (seven inches) with their legs. Tarantulas are not, as most people think, poisonous（有毒的）spiders. They can bite, and the bite is painful, but it will not kill a grown-up. The poisonous bite of a black widow（寡妇）spider is far more dangerous.
　　Bird-eating spiders often hide in holes and under rocks during the day, but at night they creep out and hunt for insects. As you might guess from their name, they also catch birds and eat them.
　　They have another unusual ability. They can walk up windowpanes（窗玻璃）because of sticky, silky hairs on their feet that cling to glass.
