The "dragon millipede" (pictured here) is one of more than 1,000 new species discovered around the Mekong River in Southeast Asia over the last 10 years. Scientists suggest the millipede uses its bright color to warn predators of its toxicity. According to a new report by conservation group World Wildlife Fund (WWF), between 1997 and 2007, at least 1,068 new species have been discovered in the Greater Mekong, at a rate of approximately two new species a week.
