I have just read that the oldest animal found to date is a 400 year Icelandic clam. I have read that the waters in Iceland provide ideal conditions to support extreme longevity. Why though?

Best I can come up with for the moment is this.|
1. The waters around Iceland are comparatively unpolluted, partly due to sparse population, and partly due to comparatively low sea traffic.
2. They are cold, enabling greater oxygen transfer.
3. They are mineral-rich and nutrient-rich.
4. There is more food growing there in the form of plankton than in most areas because of 1, 2, 3.
5. The waters around Iceland are not layered into fixed zones, but mix up distributing the nutrients.
6. Clams appear to be fairly long-lived if not eaten or dredged up by scientists. The previous record-holders (official and unofficial) in this field were clams.
Looking to find the New Scientist article - it's in here somewhere. Trouble is, so is so much else.....
