Hello, I am birdsandbats. I am 13 and love animals. I bet you can't guess what my favorite groups of animals are.
I think one is a bird. The other is Sandbats though. They live in the Sahara and are the only known bat species which live by "flying" through sand, the same way a Marsupial Mole "swims" through sand. They have exceptionally strong sonar to allow the sound-waves to pass through the sand grains. They aren't well-known to the general public.
