#ThatsWild: Did you know frogs can glow? Well, they can. It’s called biofluorescence. And new research shows that way more frogs can glow than previously thought. All the frogs scientists tested — 528 from 151 South American species — glowed to some degree, mainly around twilight, when frogs are most active. Because the body parts that glow are involved in frogs’ signaling, researchers think biofluorescence is probably part of communication. A green glow is likely related to their communication with each other, since frog eyes are sensitive to that color, while an orange glow may have evolved as a message to predators.
