On this episode of the Naturalist, Bernie Wides and Carol Butler are talking about a glowing natural phenomenon- bioluminesence! Tune in to hear how Bernie and Carol were inspired by the new exhibit at the American Museum of Natural History called Creatures of Light: Nature's Bioluminesence. Bernie and Carol discuss the many facets that compose light: energy, particles, speed, and wavelengths galore! Hear more about he exhibit, what types of critters produce bioluminescent light, and what lurks in the depths of the oceans. This episode has been brought to you by Fairway Market.
"One purpose [of fireflies flashing patterns] is to identify themselves as a potential mate, as being of the same species. So the patterns are signals to the opposite sex." --Carol Butler on The Naturalist
