In Australia no 1 the white tail. They poison your skin & the flesh gets eaten away by the venom. You are left with a holey crater that is black & red & sometimes never heals properly. No 2 the huntsman spider. A guy I use to know use to eat (swallow them whole) for a party trick. One time he got very sick from it & was hospitalized. I also saw him eat a kids pet goldfish at another party. He got kicked out of that party after handing over $20 for another fish. He was wacky in my book. the red back spider. found in outside thunder boxes, under sheets of tin roofing & are poisonous also. there was a song "there was a red back on the toilet seat." more Aussie humor.
