At Verkhoyansk, in eastern Siberia, the temperature frequently plunges to 90 degrees F below zero. If a person ventures outdoors without a mask or warming device, their breath will freeze in the air and fall to the ground. Moments later the mecury slid back down to the mid 120s. When they hibernate, some bats drop their body temperature to just a few degrees above freezing. It can be fatal to them if they are disturbed during hibernation because it throws their bodies into shock.
Bats are the mascots of cave explorers.
Bats are the primary pollinators through most of the tropics and many deserts. Without them, many plants would not survive as a species. Plants that specialize in bat pollination bloom at night. This includes many important fruit trees in the tropics and cacti species in the deserts. Bats are not blind and have decent eyesight.
