I just found out yesterday about how amazing the immune system of bats is they are practically immortal almost nothing makes them sick! But then it's confusing that bats in my region are being killed off by white nose syndrome. Fungus on their nose wakes them from hibernation and causes them such stress it eventually kills them. Which actually does make sense since the theory is bats do so well immunity-wise because of the large swing in their body temperature range. A bat's temperature drops very low when hibernating then when they fly it shoots up very high. http://www.popsci.com/bats-immune-systems-are-totally-unique http://www.popsci.com/bats-immune-systems-are-totally-unique
