It’s that time of year where you start seeing spooky decorations everywhere including bats! Very popular Halloween item. But why do bats hang upside down?
One popular theory on the internet is that since bats do not have legs they would never be able to produce enough energy to get off the ground and fly like a bird would. So hanging upside down gives them an advantage to just drop down and start flapping their wings to fly. No ground needed!
Very smart, those bats.
