Here's a look at some of the most striking new species of frog, snake, lizard, bird, fish – and mammal. (8 new photos!)

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.

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".
