You ever wonder what the biological purpose of the tongue with teeth could have for the alien xenomorph? Does that weird little mouth actually eat or does it just grab onto food and or help to kill it? Does it have its own seperate digestive track? Or even its own seperate brain? I kind of doubt that last one, but you never know. I'd kind of like a tongue like that. I mean, not to eat things, but you know, it is kind of phallic and I bet chicks would dig it. Like way more than haiku poetry.
