Clam, 405, is oldest animal ever. It has been christened Ming and it's officially the oldest animal to have ever lived. A British scientific team discovered the 405-year-old clam, named after the Chinese dynasty and not the former Liberal Democrat leader, at the bottom of the ocean, and hope its longevity will reveal the secrets of ageing.
Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that live as infauna, spending most of their lives partially buried in the sand of the ocean floor. In particular, edible infaunal bivalves are often called clams. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do). In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. Many edible clams such as palourde clams are oval or triangular; however, razor clams have an elongated parallel-sided shell, suggesting an old-fashioned straight razor. Some clams have life cycles of only one year, while at least one may be over 500 years old.
