Everything about Arctica Islandica totally explained
Arctica islandica, commonly known as the
ocean quahog, is a
marine bivalve mollusk native to the
North Atlantic ocean.
Arctica islandica is also known as the Icelandic cyprine, mahogany clam, mahogany quahog, black quahog, and black clam.
In 2006 and 2007, separate specimens collected off the coast of
Iceland were found to be more than 400 years old, making the
Arctica islandica clam the
longest lived animal species ever recorded.
Longevity
In October 2007, researchers from
Bangor University in
North Wales determined that an ocean quahog clam dredged off the Icelandic coast was between 405 and 410 years old by drilling through and counting rings on its shell (a technique known as
sclerochronology). This made it the
longest-lived animal on record.
The clam was nicknamed "Ming" after
the Chinese dynasty that ruled when the clam settled (the
mollusc equivalent of being born). The researchers are uncertain how long the clam – which died during the assessment process – may have lived had it been left on the ocean floor.
Help the Aged, a UK based charity, has contributed
£40,000 towards studying quahog longevity.
