In June 2021, German researchers discovered three new species of frog in the Amazon, one of which has been dubbed a "zombie frog."
Raffael Ernst, an amphibian and reptile expert, has described how the team dug out the frogs to Deutsche Welle. Ernst explained that the frogs are not called zombies because they look like zombies. Instead, they are plump-looking creatures of about 1.5 inches with pointy noses and orange spots. Apparently, researchers chose the name because the researchers looked like zombies while digging them out from the mud with their hands.
The nocturnal amphibian species called Synapturanus zombie can be found in French Guiana and the state of Amapá in Brazil. The species called Synapturanus mesomorphus can be found in Guyana and adjacent Venezuela, and Synapturanus ajuricaba can be found in northern parts of Amazonas and Pará (Brazil).
Limited scientific attention has been given to this genus. Their habitats are difficult to access, and their sounds are difficult to differentiate. Ernst has explained that amphibians are susceptible to water quality, habitat destruction, and disease, which can make them easily endangered.
