GREEN VIPER

"We don't know of any other place on the planet that has the same rate of discovery," said Stuart Chapman, director of WWF's Greater Mekong Programme, in a statement. The Greater Mekong includes areas of Myanmar (Burma), Laos, Vietnam, Thailand, and Cambodia.
Discovered in northeastern Thailand in 2002, the newfound snake species grows to about 4 feet (130 centimeters). Like all pit vipers, it hunts prey by sensing heat through small pits in the sides of its face.
