According to a new report released by the World Wildlife Fund (WWF), A soul-sucking ‘dementor’ wasp, a bat with long fangs, a stealthy wolf snake, a color-changing thorny frog, and the world’s second longest insect are among the 139 new species discovered by scientists in the Greater Mekong region in 2014.

The list is comprised of 99 plants, 23 reptiles, 16 amphibians, nine fish, and one mammal. All are detailed in the report “Magical Mekong” and WWF researchers say many of these species are already at risk. Those at risk include a feathered coral, four moths named after Thai princesses, a color-changing thorny frog and two orchids discovered already being traded. This brings the total number of new species discovered in the Greater Mekong to 2,216 between 1997 and 2014. That’s an average of three new species discovered per week.

“The Greater Mekong’s unique ecosystems are truly the gift that keeps on giving, providing sanctuary for a treasure trove of species and critical benefits for millions of people across the region,” Teak Seng, Conservation Director for WWF-Greater Mekong, said. “As Magical Mekong reveals, the scientists behind these discoveries feel they are racing against the clock to document these species and strongly advocate for their protection before they disappear.”
