SYDNEY, NSW - JANUARY 23: A Redback Spider is pictured at the Australian Reptile Park January 23, 2006 in Sydney, Australia. The Redback, probably Australia's best-known deadly spider is found all over Australia and is a close relative of the Black Widow Spider from the U.S. Only the female Redback is considered dangerous, with their venom containing neurotoxins, which works very slowly. Fatalities, even from untreated bites, are rare. Australia is home to some of the most deadly and poisonous animals on earth. (Photo by Ian Waldie/Getty Images)
