Ming the clam is 'oldest animal'

A clam dredged up off the coast of Iceland is thought to have been the longest-lived creature discovered.

Scientists said the mollusc, an ocean quahog clam, was aged between 405 and 410 years and could offer insights into the secrets of longevity.

Researchers from Bangor University in north Wales said they calculated its age by counting rings on its shell.

According to the Guinness Book of Records, the longest-lived animal was an Arctica clam found in 1982 aged 220.
