there is a mystery that i went to the per yo youuvian amazon. of the best thing about working in the amazon rain forest is the road along the way. join me on the expedition that's about to get wet, wild and a little bit muddy. the peruvian amazon, a huge population of endemic plant and animal species, meaning they are found nowhere else on the earth. this makes it one of the most beautiful and pristine places around. about six months ago the researcher here at the tamba pata research center took a picture and posted it on the internet. little did he know the huge amount of attention it would get as a group of amateurs and experts tried to figure out what it was. we're trying to figure out what's making it. all right, we are reaching the island where this thing was just found a few months ago and we just found 20 of it. what is the action? >> catching a human in the action of making it. >> this thing has really confused me bececse i keep going between it being possibly a spider or maybe some weird spider might that nobody's ever found before. eve
