to attach themselves to roost sites, but instead use a form of wet adhesion by secreting a body fluid at their pads.Brown University News, December 2009,
Bats Don’t Use Suction After All
/ref> The ankle and wrist pads of the bat are controlled by muscle contraction and allow the bat to separate the pads to reduce the adhesive effect. This allows the bats to climb with ease and to remove themselves from surfaces after sticking. Due to this property the Madagascar sucker-footed bat is one of the few bat species that roosts with its head up rather than upside down. This is so the bat does not accidentally lose control of the adhesive pads while it is sleeping due to the muscle tension associated with roosting upside down. Because of their unique habitat, sucker-footed bats don't carry
