I found these three videos on youtube showing a kind of weird undistinguishable thing floating in the McGraw pond near Oakland in the US State Maine.
Is it a fish? A snake? A piece of alien? A rotten plant?
According to the uploaders, this weird and stinky piece of desintegrating material is boneless and has stringy meat to it when they cut into it.
Well looking on the web, I figured out this weird piece of rotten material could be a decaying piece of lily root.
Look at the similarity of the form and colors.
What do you think?
