From a devilish-looking bat to a frog that sings like a bird, scientists have identified 126 new species in the Greater Mekong area, the WWF said in a new report detailing discoveries in 2011. But threats to the region's biodiversity mean many of the new species are already struggling to survive, the conservation group warned. "The good news is new discoveries. The bad news is that it is getting harder and harder in the world of conservation and environmental sustainability," Nick Cox, manager of WWF-Greater Mekong's Species Programme, said.
