Sequoia Glowing Millipede

Motyxia sequoiae photographed by nothing but its own green-blue light, during an eight-second exposure. This blind millipede lives in the forest floor of California's southern Sierra Nevada, and it glows steadily rather than flashing. The light is a warning: Motyxia can ooze cyanide when disturbed, and in a 2011 field experiment in Giant Sequoia National Monument, glowing clay models were attacked about half as often as dark ones. It is bright colors for a night shift.
