Nature Red in Tooth and Claw

The next time some pie-eyed city dweller tells you that Nature is all touchy-feely and Disney-esque cuteness, you can disabuse him/her with one of these tales.  (In a funny coincidence, I had just watched "The Ghost and the Darkness" on Netflix the other night.)  Aaaaaand, since I have a wicked sense of humor, suddenly the lyrics of Hall and Oates are rampaging through my head.  What song of theirs?  Come on, do you really have to ask?
