When the night falls, the sky comes alive. A flutter of wings that, for some, is the stuff of nightmares. One in every four mammals on the planet is a bat. But fear for these creatures is often misplaced. Not all bats are blood-sucking beasts. It's only the Vampire bat that has that disgusting habit, and it's given the others a bad rap. The world of bats is incredibly diverse with some beautifully bizarre adaptations. There are the Sucker-footed bats that crawl vertically up leaves, the Tent-building bats that construct their homes from a surprising material, and the Bulldog bats that have become expert fishermen. Things get eerie when we meet the bat with a tongue twice as long as its body, become engulfed in a bat blizzard of ten million winged beasts that fill the sky, and finally, see the ultimate daredevil that has evolved to hunt the deadliest scorpions on the planet.
