Alien animals on earth
Meet Promachoteuthis sulcus, a bizarre creature straight out of your nightmares. As you can see, this thing looks like it has freakishly human looking teeth. It's a species of promachoteuthid squid and only one specimen has been found to date. It was captured in the Southern Atlantic Ocean at a depth of 2,000m in 2007. Just imagine what else is lurking in our oceans!
