Top 10 Creatures that Glow in the Dark

The Land Snail, Quantula Striata


While there are plenty of glowing aquatic molluscs, there is only one snail on land known to produce light: the tropical species, Quantula striata. In fact, it is the only land gastropod (among thousands of snails and slugs) known to be bioluminescent. It is so elusive (as many snails are) that a picture in the dark could not be procured. The eggs have been observed as having globules that glow in the dark continuously. Juvenile and adult snails can produce short bursts of green light. While many land snails communicate through pheromones, it is suggested this tropical species may also use its bioluminescence as a form of communication.
