"Mammals Found to Frequently Exhibit Fluorescence, Scientists Reveal"
Scientists have discovered that fluorescence is more common in mammals than previously thought. Researchers conducted tests on preserved and frozen specimens and found 125 fluorescent species of mammal from every known order. They determined that the fluorescence was a real biological phenomenon and not caused by the preservation process. The study suggests that fluorescence may be a default property of unpigmented hair and could enhance visual signaling in animals, especially in poor light conditions. Nocturnal and terrestrial species were found to be more likely to fluoresce.
