Single cell organisms are not born and do not die in that sense, so in a way any individual amoeb could be said to be millions of years old. "The Hydrozoan species Turritopsis nutricula is capable of cycling from a mature adult stage to an immature polyp stage, and back again, indefinitely. This means there is, theoretically, no limit to its life span." This is also stretching the definition to the limit. "A specimen of the Icelandic Cyprine Arctica islandica (also known as an ocean quahog), a mollusk, was found to have lived 405 years and possibly up to 410. Another specimen had a recorded lifespan of 374 years." "Some koi fish have reportedly lived up to over 200 years, the oldest being Hanako, died at an age of 226 years on July 7, 1977. Some unconfirmed sources estimated Bowhead Whales to have lived up to 210 years of age. If proven this would make them the oldest mammals. Tu'i Malila, a Radiated tortoise died at an age of 188 years in May 1965." http://en.wikipedia.org/wiki/List_of_long-living_organisms#Animals May 15 08, 12:35 PM

Can you imagine living for four centuries? A team of scientists from Bangor University's School of Ocean Sciences believe they have found an animal which did just that, a quahog clam, Arctica islandica, which was living and growing on the seabed in the cold waters off the north coast of Iceland for around 400 years. http://www.sciencedaily.com/releases/2007/10/071028100032.htm May 15 08, 5:15 PM
