      I’m not really sure what you mean!

      Do you mean that the fact they’re blind doesn’t matter because it’s dark at night?

      Bats are blind so they use a type of sonar to get around. They make a sound and listen for the echos of the sounds bouncing off walls (or caves I suppose) to figure out where they are. It is called “echo location”. You can hear what they sound like here: http://upload.wikimedia.org/wikipedia/commons/9/94/Pipistrellus.ogg (kind of squeeky).
