It's a good thing Giant tortoises live as long as they do as they average only .25 MPH. As far as plants go, Bristlecone pines found in the White Mountains in California, have the longest life span of any plant or tree. One such pine named the Methuselah tree is estimated to be 4,725 years old. If you consider clams as animals and not just ingredients for soup then the quahog clam has quite an impressive life span. In 2007 scientists found a quahog clam off the north coast of Iceland which they believe to be 400 years old.
Californiaâs storied redwood trees are probably best-known as the tallest trees in the world, towering 350 to 400 feet tall. The conifers are a fast-growing tree, growing 3 to 5 feet per year in the first five years and reaching 90 feet tall by 25 years. The average life span of a redwood tree is more than 600 years. Only two species of redwood trees are still found in North America, the coast redwood and the giant sequoia.
