What in the actual hell? It’s a short video so there is literally no context, but this is absolutely insane. I guess South America is really as wild as I hear.
According to the Youtube description from the woman who took the video, Amanda Klass:
I recorded of a 6ft long Yellow Tailed Cribo snake being tackled and subdued by a researcher, Renata Leite Pitman, who was at Los Amigos Biological Station in Peru. – Amanda Klass
