The Shocking pink dragon millipede (Desmoxytes purpurosea), is a new species of dragon millipede named for its vivid pink color. It was formally described in 2007 from a specimen collected at the Hup Pa Tard limestone cavern in Thailand, within the Greater Mekong. The largest species of its genus, the adult millipede is approximately 3 cm (1.2 in) long. It lives in the open on leaf litter. It becomes gregarious after rain showers. The millipede has glands that produce hydrogen cyanide to protect it from predators, a fact advertised by its aposematic color. Because it produces cyanide, it smells like almonds.
