A psychedelic gecko and a monkey with an "Elvis" hairdo are among 208 new species described last year by scientists in the Mekong River region of Southeast Asia.
The region is home to some of the world's most endangered species, including tigers, Asian elephants, Mekong dolphins and Mekong giant catfish, the group said.
The Mekong flows through China, Myanmar, Laos, Thailand, Cambodia and Vietnam.
In October, WWF announced Vietnam has lost its last Javan rhinoceros, making the 40 to 60 Javan rhinos living in Indonesia the last remaining members of their species.
