The Oldest Animal on Earth

This item updates a fascinating story I mentioned in my new book Shadows of Existence. It was always presumed the great whales lived to be quite old for mammals, maybe 60 or 70 years, but 200+? The question was raised when bowhead whales were killed legally by aboriginal people of the Arctic and found to have stone harpoon points, out of use for over a century, embedded in them. Analysis of amino acid ratios in the preserved eyes of some of these whales indicate, according to Jeffrey Bada of Scripps Institute, that "About 5 percent of the population is over a hundred years old and in some cases 160 to 180 years old." One male may have been over 200. Bada said we don't know if bowheads are unique or if studies of other whale species may indicate similar longevity.
