What makes animals glow? Some of them, like jellyfishes and scorpions, glow under ultraviolet lights because of naturally occurring proteins or other materials. Other animals, such as monkeys or puppies, glow because scientists have added new proteins into their DNA. The glowing mice in the photo above received DNA with the glowing protein from their father.
