Flying squirrels glow pink, thanks to fluorescence

The team took photographs under visible and ultraviolet light, compared them to non-gliding squirrels, and measured the intensity of fluorescence. While other animals fluoresce—puffins’ bills and chameleon’s bones give off an eerie, blue glow under UV light, for example—the only other mammals known to have fluorescent fur are about two dozen species of opossum. Jim Kenagy, curator of mammals at University of Washington’s Burke Museum and not involved in this study, is curious to see if the fluorescence is found in flying squirrel species elsewhere in the world.
