Although the Great Barrier Reef can be considered the largest life form on Earth, it is made of many different organisms. The response about the fungus in Oregon is the correct one, as this is only one single organism. To know more about it, I suggest you check out www.news.bbc.co.uk/2/hi/science/nature/869808.stm

well i think graffie on earth and whale in sea is the largest living thing.

I also always thought it was the redwood tree. Maybe that's the longest living thing. You ask a very interesting question, taurusgirl.
