Clam claims oldest animal record

---

A clam that lived on the seabed in the frigid waters off Iceland's north coast has been hailed as the longest-lived animal ever discovered.

The mollusc, which is thought to have lurked beneath the waves until at least the age of 405, would have been a juvenile when Galileo picked up his first telescope, Hamlet was first staged and the gunpowder plot failed to blow up King James I.

The Arctica islandica clam was plucked from 80m-deep water by researchers at Bangor University in Wales, who were dredging the north Iceland shelf for the creatures. By studying their shells, the scientists hope to learn how the marine environment has changed in recent centuries.

The clam was alive when it was brought to the surface, but at that point, the researchers had no idea how old it was. Only after cutting through the shell and counting annual growth rings under a microscope did they date the mollusc to between 405 to 410 years old.

"Its death is an unfortunate aspect of this work, but we hope to derive lots of information from it," said Al Wanamaker, a postdoctoral scientist on the university's Arctica team. "For our work it's a bonus, but it wasn't good for this particular animal."

Marine biologists are unclear why the particular species of clam, Arctica islandica, is so long-lived. According to the Guinness Book of Records, the current claim for the oldest animal goes to another Arctica clam that lived for 220 years, though an unofficial record is held by yet another that lived to 374 years old.

I expect they did it a favour. When you're 405 years old, you spend your days just waiting to die!

That reminds me (tenuous connection, this), I was at the cinema last night and there were some kids who were clearly only about 12 trying to get into a 15 movie. Oddly enough, they were unable to produce any ID that proved their age. I suggested that they be cut in half so that we could count the rings. So my facetiouness has the same basis as Welsh science. Good, eh?
