Just watched the documentary "Fastest Claw in the West"....I'll post a review soon, but I can say that it was a darn good documentary, including interactions with several different crabs (and you know who wins), three cephalopods (with a funny segment where a mantis tries to subdue a fleeing Cuttlefish-type (Sepioloidea?) that had been poaching shrimp close to its burrow), one big fish, and one nosy human (doc caldwell). oh, yeah, it did manage to solve a rubik's cube in the end, much to the surprise of my wife - LOL.
