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.

In 2007 scientists found a quahog clam off the north coast of Iceland which they believe to be 400 years old.
