Desmoxytes purpurosea, commonly known as the shocking pink dragon millipede or dragon millipede, is a spiny and toxic millipede named for its vivid pink color. It was formally described in 2007 from a specimen collected at the Hup Pa Tat limestone cavern in the Uthai Thani Province of Thailand. Among 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. Large numbers of them occur after rain showers. The millipede has glands that produce hydrogen cyanide to protect it from predators, which causes it to smell like almonds. Its toxicity is advertised by its aposematic color.
