I am no more sure bats are classifiable as mammals. Bats are immune to a lot of viruses at a deep cellular level. Bats do fly, but there is a weird behavior with their oxygen reduction in order to allow them to fly. They are not as light as birds, they are a lot heavier, even their bones are heavier too, and their ability to fly requires a lot of more energy, and, due to the cellular stress to produce this huge amount of energy, it must happen something at the cellular level, something that is actually completely unknown because if we apply this to "a common mammal" it will for sure cause a lot of serious DNA damages that are impossible to repair, and for sure cancer will arise. Yet it doesn't happen in bats. Why? What does make their DNA so strong? What do bats use to repair their DNA? And how can they be so immune to viruses? |

From my reading, what makes bats an extreme case is their ability to distribute things they collect which don't harm them. |

That makes studying them pretty interesting. I don't think we quite understand yet what their "secret sauce" really is. |

If bats didn't have a weird immune systems they probably wouldn't exist as they tend to hang in dense groups in the order of millions. |
