The Greater Mekong Region
Wet tropical mountains and valleys like these, the Dawna-Tenasserim mountains on the Thai-Myanmar border, are fertile grounds for the discovery of species that are new to science. Heavily forested and remote, the incredible biodiversity of the region is nonetheless threatened by dam- and road-building projects, logging and agriculture, and unsustainable hunting.
Bare-faced Bulbul
"Asia's only bald songbird," as WWF describes it, the bulbul was found in 2009 in Laos by the Wildlife Conservation Society and the University of Melbourne. While its karst limestone habitat may be at risk fro quarrying (it was found on a scientific expedition sponsored by Australian mining company MMG), its relatively large range and apparently strong population numbers mean it is not at risk of extinction, according to Birdlife International.
Stone-Sucking Fish
Found in These new species of the Oreoglanis genus were found in rocky, fast-flowing streams all over Thailand, these Oreoglanis fish are known as "stone-sucking" fish to the locals.
Eleryi's Tube-Nosed Bat
A bat first described in 2009 by scientists at the Harrison Institute, Eleryi's tube-nosed bat is native to Vietnam.
Appleby's Leaf-Litter Toad
This tiny Asian leaf-litter toad was discovered chirping beneath the leaves of a forest in central Vietnam in 2007 by Jodi Rowley, a researcher at the Royal University of Phnom Penh. Leptolalax applebyi isn't named for the American fast-food chain, but for Robert Appleby of ADM Capital Foundation, which helps fund much of Rowley's research. Appleby was reportedly flattered despite being "unsure about the resemblance".
Fangless Snake
Named for Nguyen Van Sang, a scientists with the Institute of Ecology and Biological Resources in Hanoi, this Coluberoelaps nguyenvansangi is a fangless snake discovered in Vietnam on a 2003 WWF expedition, and described for the first time by scientists in 2009.

The frogs fangs protrude from its bottom jawbone and it is known to be an opportunistic eater, lying and waiting for prey in streams. The species is known to eat birds as feathers were found in its feces. This species was one of the new species discovered in the Greater Mekong region of Southeast Asia during 2008.
Nonggang Babbler
