Bats glow under infrared light due to a phenomenon called fluorescence. This occurs when certain molecules in their fur and wings absorb ultraviolet light and then re-emit it as visible light. This adaptation may help bats to communicate with each other, navigate in the dark, or potentially even deter predators.
