Jesus Christ, nature can be so damn beautiful sometimes... Animals and humans aren't so different after all. Like the anaconda, vomiting is exactly how every intimate encounter I've had with a cow has ended as well.
I'd like to see a video whereby an anaconda swallows an entire human, but unbeknownst to the beast the human is Wolverine (or just a guy with a knife) and the dude tears the anaconda apart from the inside out. I bet that video would go viral as fuck. And yeah, if you were looking for a reason to never enter a Brazilian jungle or any jungle at all, this could be it.
