The recent discovery of a 405-year-old quahog clam in the Arctic is being held as further evidence that quahogs are the world’s longest-living animals.

An article on the National Geographic website says that the clam, which was dredged from 262’ of water off Iceland, “is being hailed as the world’s longest-lived animal.” Its age was determined by counting the annual growth rings on the clam’s shell. A 220-year-old quahog taken from American waters in 1982 holds the current title for longest-lived animal in the Guinness Book of World Records, but unofficially, the record belongs to a 374-year-old Icelandic clam housed in a German museum.
