There are certain times when the woods begin to glow. Sometimes they glow so much that people call the Park Service and ask them to send a hazmat team. What they're actually seeing is foxfire. And although we know how it happens, we don't know exactly why.

The above picture shows the first photo of the famous Milky Seas Effect. It's a luminescence that turns thousand-mile patches of ocean a glowing milky blue.

Measuring only about a foot and a half long, the lanternshark may seem distinctly less impressive than its larger shark cousins. But this diminutive fish has mastered the art of bioluminescence, concealing themselves from prey while challenging any potential predators.

Unfortunately, those properties are deadly. These are the jack-o-lantern mushrooms, and their gills have a faint, but beautiful, bioluminescence. The mushrooms are intriguing in theory, but they're lethal when it comes to actual practice.

If you're an aquatic mammal, how do you hunt in the darkest seas, where light can't penetrate? Dolphins have it easy with their echolocation, but what about the other animals with much more limited senses? They chase after critters that provide their own light.

No really, look. The resemblance is uncanny. Right down to the little bandolier.

Scientists from Syracuse University have found a way to mimic the bioluminescent qualities of fireflies, a development that could lead to products with multicolor strings of light that don't require electricity or batteries to glow.

You might think a stomach that lights up would be a liability when you're trying to avoid getting eaten — but the glowing bellies of tiny sharks are helpful in camouflaging them from predators lurking below, researchers say.

Really, one of the key issues with sushi is that it doesn't glow under black light. To solve that problem, the Center for Genomic Gastronomy is using genetically modified fishies from the pet store to create tasty treats that will be perfect for your next rave.

This awesome photo is of a newly discovered deep sea worm, Swima fulgida. Measuring just over an inch long, this little guy lives 9,000 feet underwater and escapes predators by flinging homemade "bombs" at its enemies.
