Ming (clam)
Ming ( 1499–2006), also known as Hafrún, was an ocean quahog clam (''Arctica islandica'', family Arcticidae) 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 precisely determined. Thought to be 405 years old, Ming was later determined to be 507 years old, although the clam had previously been killed to make this determination. The size of the clam was 87 mm × 73 mm. Name The clam was initially named Ming by '' Sunday Times'' journalists, in reference to the Ming dynasty, during which it was born. Later, the Icelandic researchers on the cruise which discovered the clam named it Hafrún, a woman's name which translates roughly as 'the mystery of the ocean'; taken from , 'ocean', and , 'mystery'). The actual sex of the clam, however, is unknown, as its reproductive state was recorded as "spent". Original discovery T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctica Islandica
The ocean quahog (''Arctica islandica'') is a species of edible clam, a marine bivalve mollusk in the family Arcticidae. This species is native to the North Atlantic Ocean, and it is harvested commercially as a food source. This species is also known by a number of different common names, including Icelandic cyprine, mahogany clam, mahogany quahog, black quahog, and black clam. The typical ''Arctica islandica'' resembles the quahog, but the shell of the ocean quahog is rounder, the periostracum is usually black, and on the interior of the shell, the pallial line has no indentation, or sinus. Unlike the quahog, which lives intertidally and can be collected by clam digging, this species lives subtidally, and can only be collected by dredging. They grow to sizes exceeding 50 mm or two inches shell height. An individual specimen was reported to have lived 507 years, making it the longest-lived non-colonial metazoan whose age was accurately known. Life cycle and longev ...

Hinge Line
A hinge line is an imaginary longitudinal line along the dorsal edge of the shell of a bivalve mollusk where the two valves hinge or articulate. The hinge line can easily be perceived in these images of a mussel shell and an ark shell.Invertebrate Paleobiology on-line syllabus on Bivalves, by Dr. Burt Carter, Georgia Southwestern State University, at: http://itc.gsw.edu/faculty/bcarter/paleo/labs/moll/biv2.htm The hinge teeth Hinge teeth are part of the anatomical structure of the inner surface of a bivalve shell, i.e. the shell of a bivalve mollusk. Bivalves by definition have two valves, which are joined together by a strong and flexible ligament situated on the hing ..., structures which control the articulation of the valves, are often but not always situated along the hinge line.

Individual Wild Animals
An individual is that which exists as a distinct entity. Individuality (or self-hood) is the state or quality of being an individual; particularly (in the case of humans) of being a person unique from other people and possessing one's own needs or goals, rights and responsibilities. The concept of an individual features in diverse fields, including biology, law, and philosophy. Etymology From the 15th century and earlier (and also today within the fields of statistics and metaphysics) ''individual'' meant " indivisible", typically describing any numerically singular thing, but sometimes meaning "a person". From the 17th century on, ''individual'' has indicated separateness, as in individualism. Law Although individuality and individualism are commonly considered to mature with age/time and experience/wealth, a sane adult human being is usually considered by the state as an "individual person" in law, even if the person denies individual culpability ("I followed instruct ...

2006 Animal Deaths
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler". Six is a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Long-living Organisms
This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum lifespans. For a given species, such a designation may include: # The oldest known individual(s) that are currently alive, with verified ages. # Verified individual record holders, such as the longest-lived human, Jeanne Louise Calment, or the longest-lived domestic cat, Creme Puff. The definition of "longest-living" used in this article considers only the observed or estimated length of an individual organism's natural lifespan – that is, the duration of time between its birth or conception, or the earliest emergence of its identity as an individual organism, and its death – and does not consider other conceivable interpretations of "longest-living", such as the length of time between the earliest appearance of a species in the fossil record and the present (the historical "age" of the species as a whole), the time betwee ...

Carbon-14 Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calcu ...

Morgunblaðið
''Morgunblaðið'' (, ''The Morning Paper'') is an Icelandic newspaper. ''Morgunblaðið''s website, mbl.is, is the most popular website in Iceland. History ''Morgunblaðið'' was founded by Vilhjálmur Finsen and Ólafur Björnsson, brother of Iceland's first president. The first issue, only eight pages long, was published on 2 November 1913. On 25 February 1964, the paper first printed a caricature by Sigmúnd Jóhannsson which featured the first landings on Surtsey. He became a permanent cartoonist for ''Morgunblaðið'' in 1975 and worked there until October 2008. In a controversial decision, the owners of the paper decided in September 2009 to appoint Davíð Oddsson, a member of the Independence Party, Iceland's longest-serving Prime Minister and former Governor of the Central Bank, as one of the two editors of the paper. In May 2010, Helgi Sigurðsson was hired as the papers cartoonist. He became known for controversial drawings on topics such as immigration, refugee ...

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...
