Species Hot Spot
Between 1997 and 2007, more than 1,000 species previously unknown to science were discovered in Southeast Asia's Greater Mekong region, according to a report by the World Wildlife Fund. That's about two new species a week. The Greater Mekong has the highest concentration of different ecosystems in mainland Asia, and the Mekong River supports more wildlife per square mile than the Amazon. Newly documented flora and fauna include, clockwise from upper right, a woolly bat (Kerivoula titania); Aeschynanthus mendumiae; Gumprecht's green pit viper (Trimeresurus gumprechti); and the dragon millipede (Desmoxytes purpurosea).
