The theory that people seem to think is like most plausible is that the fluorescence could actually make these animals less visible specifically to predators. And that's kind of interesting because pretty much all the mammals that we've found to display this trait are prey species they're not predators. I mean is it just a random pink squirrel moment? Do we know what it means that all these mammals can do this? We have no idea what it means. So yeah I don't think we even know in terms of how it evolved or whether it did evolve independently or whether it's a trait that's conserved in particular linear disease or anything like that.
An accidental discovery on a nighttime walk led one scientist and his team to wonder: How many mammals glow under ultraviolet light? The list keeps growing, but scientists still aren’t sure why these furry creatures glow.
