No, mammals.
We get occasional glimpses of bats as we live in the vicinity of wetlands.
Oh and I've mentioned it recently, but in case you missed it - bats echolocate [ultrasonic squeaks], they don't see as we do, I believe echolocation creates and effect in which the animal gets a feel of what's within view, the edges.
Schalke can do damage to Barca, although I wonder if they'll have the balls to convert their chances. I wonder if they truly believe, is there a true conviction within the group that they can defeat all those big names, the players, the club.
