Scientists discovered 163 new species in Southeast Asia’s Greater Mekong region last year，but all are at risk of extinction due to climate change，the WWF said in a report released Friday.
The newly discovered creatures include a bird?eating frog with fangs (毒牙)，a bird that would rather walk than fly and a gecko (壁虎) whose alien appearance inspired the report’s title of “Close Encounters”，the conservation group said.
The report was released ahead of major UN talks on climate change in Bangkok next week，which are being held before a make?or?break summit in Copenhagen this December.
“Some species will be able to adapt to climate change，and many will not，potentially resulting in massive extinction，” Stuart Chapman，director of the WWF Greater Mekong program，said in the report.“Rare and endangered species like those newly discovered are especially vulnerable (易受伤害的) because climate change will further shrink their already restricted habitats，” he said.
“The new discoveries in 2010 include 100 plants,28 fish,18 reptiles,14 amphibians,2 mammals and a bird，”the WWF report said.The area spans Cambodia，Laos，Myanmar，Thailand，Vietnam and China’s Yunnan Province.
“Among the new species is the bird?eating fanged frog，which remains hidden in a protected area of Thailand despite the fact that scientists are studying there for 40 years，” the report said.
The tiger?striped pit viper was discovered accidentally on an island off the coast of Vietnam when a scientist was looking? for a lizard and his son pointed out that his hand was on a rock right next to? the snake’s fangs.“We caught the snake and the gecko and they both proved to be new species，” researcher Lee Grismer of La Sierra University in California was quoted as saying in the report.The leopard gecko，found on another Vietnamese island，has the coloring of a leopard and bizarre orange，cat?like eyes and thin legs.
The Greater Mekong region has proved a rich area? for scientists.The WWF said in December 2010 that it had found 1,068 new species there between 1997 and 2009.
