Ming (clam)
Ming ( 1499 – 2006) was a nickname given to a specimen of the ocean quahog clam (''Arctica islandica'', family ''Veneridae''), that was dredged off the coast of Iceland in 2006 and whose age was calculated by counting annual growth lines in the shell. Ming was the oldest individual (non-colonial) animal ever discovered whose age could be accurately determined.〔 Originally thought to be 405 years old, Ming was later determined to be 507 years old.
==Original discovery==
Ming was dredged off the northern coast of Iceland in 2006. In 2007, on the basis of counting the annual growth bands on the cross-sectional surface of the hinge region of the shell, researchers announced that the clam was 405 years old.〔Wanamaker AD ''et al''. (2008) (Very long-lived mollusks confirm 17th century AD tephra-based radiocarbon reservoir ages for north Icelandic shelf waters. ) ''Radiocarbon'' 50(3): 399-412〕 The research was carried out by researchers from Bangor University, including Dr. Alan Wanamaker, Dr. Paul Butler, Professor James Scourse and Professor Chris Richardson. It is not known how much longer Ming might have lived had it been left in place on the ocean floor.〔
It was named after the Ming dynasty, during which it was born.〔 Professor Richardson said that the existence of such long-lived species could help scientists discover how some animals reach such advanced ages.〔
