flying mice are blind?

Often associated with darkness, witches and black magic, bats are a subject of myths and delusions which expose their harbingers of a trouble living in night. Though people often think that bats are blind because they hunt only at night, actually all species of bats can see though their sight is poorly developed. To compensate this shortcoming they have developed excellent sense of smell and hearing, and can use echolocation and a hydrolocation for orientation and hunting in night. They possess so exclusive system of a sound location that they often hear better, than sonars of a military class that it is surprising for such little animals.
