10 AMAZING Bat Facts-~ The average bat will probably outlive your pet dog. The average lifespan of a bat varies, but some species of brown bat can live to be 30 years old. Considering that other small mammals live only two years or so, that's impressive. ~
~ An anticoagulant found in vampire bat saliva may soon be used to treat human cardiac patients. The same stuff that keeps blood flowing from vampire bats' prey seems to keep blood flowing in human beings, too. Scientists in several countries are trying to copy the enzymes found in vampire bat saliva to treat heart conditions and stop the effects of strokes in humans. ~
~ The pallid bat of western North America is totally immune to the stings of the scorpions and centipedes upon which it feeds. ~
~ Contrary to popular myths, most bats have very good eyesight, have excellent echolocation so they do not become entangled in human hair, and seldom transmit disease to other animals or humans. ~
~ Vampire bats adopt orphans, and are one of the few mammals known to risk their own lives to share food with less fortunate roost-mates. ~
~ Little brown bats can reduce their heart rate to 20 beats per minute and can stop breathing altogether for 48 minutes at a time while hibernating. They may hibernate for more than seven months if left undisturbed, but can starve if they are awakened too many times during the winter, which causes them to run out of energy reserves before spring. ~
~ Tiny woolly bats of West Africa live in the large webs of colonial spiders. ~
~ Frog eating bats identify edible from poisonous frogs by listening to the mating calls of male frogs. Frogs counter by hiding and using short, difficult-to-locate calls. ~
~ Fishing bats have echolocation so sophisticated that they can detect a minnow's fin as fine as a human hair protruding only two millimeters above a pond's surface. ~
~ Male Gambian epauletted bats of Africa have pouches in their shoulders that contain large, showy patches of white fur, which they flash during courtship to attract mates. The Chapin's free-tailed bats have big tufts of white fur on top of their heads, which they fluff up during courtship. ~
