Quahog clam (Arctica islandica). Two halves of a quahog clam shell. This clam lives in waters around northern Iceland and is estimated to be 405 years old, making it the world's longest lived animal. The quahog age is calculated by counting annual growth rings on the shell. The distance between each ring growth may also reveal evidence of past climate change.
