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.
Red Cedars can reach 1200-1400 years of age. The average age of older cedars is 600-900 years of age depending on species and cultivar. The typical life span for a redwood tree is 500 to 700 years, although some trees live to be 2000 years old. The reason is mostly because of their super thick bark.
