You want to see http://shimmyshewobble.com/wp-content/uploads/2009/05/giant_centipede.jpg but even bigger? :cold: :sick: I'm scared.
That thing looks badass! I would totally fight a giant version of that.
Okay, the confusion between arthropods is fine. Who cares if a spider is an arachnid and not an insect? Both classes are gross, exoskeletal, have mandibles, too many legs, creepy eyes, and are little bastards. The distinction's more annoying than it is necessary. Arthropods are gross. All of them. Including crustaceans. Big ones are worse. Don't be jerks about this.
Calm down. We're just correcting some people in case they don't realize the difference. Besides no ones being a jerk about it, I don't know why your getting that idea.
