The smallest bat in the world is from Southeast Asia.This kind of bat measures about 30 millimeters in length. The world's largest bat, the Giant Golden-Crowned Flying Fox, has a wingspan of 1.5 meters.Most bats eat insects,but many feed on fruit or nectar from flowers.
Many people think bats are blind,but this is not true.Many species have very good sight.Most bats communicate and find their way by making"echolocation" (回声定位法 ) noises.They produce high-frequency noises and can estimate the distance of an object by using the sound echoes that bounce back to them. So, while bats may travel in total darkness, they"see"using sound.
Sadly, bats are widely feared and misunderstood. Most bats come out of their shelters only at nightfall. Three bat species feed on blood. Because of these qualities, bats have long been linked in many cultures to death, darkness and blood-drinking.
Yet bats are important for agriculture and our environment. They help pollinate (授粉)plants and spread seeds. They also help control insects. Bats eat huge numbers of insects,including kinds that damage crops.
For example, a brown bat can eat more than 1,000 insects in one hour.Onereport says bats save American farmers billions of dollars every year by reducing crop damage and limiting the need for chemicals that kill insects.
Over one-fifth of all bat species are under threat. They face disease and the human destruction of their natural environments.In some areas, diseases have killed nearly 100% of bat populations.
