Whitetail. All I know is that I've been bitten by them before a bunch of times (in my sleep), and despite the fact their venom doesn't have the worst possible effect on me (I feel really sick, but no ulcerating skin), I'm still paranoid. Last time I got bitten, the toxicity from the bite didn't let my body heal a papercut so I scarred from the tiniest injury ever.
Well, my unlucky Australian friend, you appear to have suffered a rare effect from a bite, since in most cases a bite normally just causes pain, swelling and itchiness.
