The beauty of a living thing is not the atoms that go into it, but how they’re arranged…we are a way for the universe to know itself.

Motyxia Sequoiae: The Glowing Millipede.

Living in the upper reaches of the Sierra Nevada, this millipede glows blue as a warning to predators that it is toxic and contains cyanide. 

All 11 species in the genus glow, however those in the lower elevations of the mountain glow less brightly. Scientists think the bio luminescence was first evolved as a means of coping with the hot environment, but later evolved into a warning sign as the creatures moved to cooler areas of the mountains.
