Bats are mammals from the order Chiroptera whose forelimbs style webbed wings, making them the only real mammals naturally capable of correct and sustained flight.
By contrast, other mammals said to travel, such as flying squirrels, gliding possums, and colugos, can simply glide for short distances.
Bats don’t flap their entire forelimbs, because birds do, but instead flap his or her spread-out digits, which are extended and covered with a skinny membrane or patagium.
Halloween and Bats
It isn’t clear how bats go to be involved in Halloween. If anyone could give a better guess,. It might be down to them flying around at night.
And presumably the ancients thought they must have held mystical powers. With bats hanging upside down and wrapping their wings around them. The ancients thought this was a sign of the witches cloak.
This being said, that’s where the power of the imagination kicks in. The ancients though they were evil and linked to witches, So there for now we associate bats with Halloween.
All though, People imagination as come a long way since then. And we know associate bats with vampires.
