A new study reveals that the color changers can also glow in the dark under ultraviolet light.
Chameleons are color-changing, tongue-whipping, eye-rolling lizards. But did you know they also glow in the dark?
A new study published this week in the journal Scientific Reports revealed just that. It's the first time researchers have reported bone-based fluorescence in vertebrates.
The proteins, pigments, and other materials that make up bones help them to glow under ultraviolet light—just think of how your florescent smile lights up under a black light. We've known that 75 percent of deep-sea creatures can glow in the dark, so this light-emitting characteristic is common in marine species.
