A leopard-like gecko and a fanged frog are among 163 new species discovered last year in Southeast Asia's Greater Mekong region, the World Wildlife Fund (WWF) announced Friday. But in its report, "Close Encounters," the environmental group also said that the species are at risk of extinction because of climate change. One of the new species, a tiger-striped pitviper (Cryptelytrops honsonensis), is shown here. They are endemic to Hon Son Island in Rach Gia Bay in the Kien Giang Province of southern Vietnam.
