Many people find bats frightening creatures. They have incredibly odd habits--like sleeping upside down, staying up all night and occasional bloodsucking. .
We characterize bats as supernatural. It's for that ability to "see" with their ears that bats are perhaps most well-known—that, and their supposed blindness, which makes echolocation(回声定位)necessary for finding and feeding on fruits and insects and other small animals. ? What if being" as blind as a bat" just meant, well, being able to see perfectly well'?
Contrary to what most people believe, bats are generally not blind at all and in fact are believed to have eyesight keener than that of most humans. Because they hunt mostly in the dead of night, when lighting conditions are, of course, very dark, bats rely on echolocation to pinpoint exact locations of prey. Instead, a bat's eyes, far from useless, are accustomed to low-light conditions to better aid in finding prey and are enhanced by their super hearing power. Being as blind as a bat doesn't sound so bad now does it?
. However, there are six species of bats that don't hang upside down. For most bats, their feet have evolved to be relaxed in a clenched position. When they're ready to fly, they let go and gain force from falling, since their little legs and wings can't give them the kind of lift birds get.
