If You Need A Nightmare Tonight, Watch This Parasite Escaping Its Host

If you need a nightmare tonight, watch this parasite escaping its host

A living praying mantis, a glass of liquid (probably water), a horsehair worm escaping out of it. This is not the first time I have seen this -- although the mantis was dead then -- but that doesn't make this video any less disgusting and terrifying, yet so fascinating that I had to watch it all.
