Amazing: Clam live up to 450 years old

Few people know that clam, also known as clam, is a bivalve mollusk, which humans use as a regular dish, has a "persistent" life creature. Scientists have discovered a "clam" living off Iceland's coast with a life of 410 years, while cells have not shown signs of aging.

In the natural environment, clam species can live up to 450 years, 6 times the life expectancy of humans. Scientists have based on the number of rings on their cover to determine life expectancy.

Clams are round, white or light yellow. Clams belong to family Veneridae. This species usually lives in coastal areas, salt water, where there is a lot of gravel. Currently, they are widely available in tropical and subtropical regions of the world.

Clam species are common in Vietnam and are widely cultured in coastal provinces from North to South. The most ideal environment of clam is sandy mud. They live right on the surface, but also when snuggled to the bottom of the sand at a depth of 3-4m.

Clams are passive species in finding food. They are unable to hunt and choose food. They maintain life and growth by filtering substances from mud, plankton and algae around them.

Clams produce all year round, however, in the rainy season, they reproduce more vigorously, because at this time, the amount of food from the rivers is much higher. This krill is separate male and female.

In the ovule of the female clam, there are on average 5, 4 million eggs, even up to 8.5 million eggs. After laying eggs in the water environment, clam larvae live floating for about a month, then sink to the bottom of the water when they become juvenile shells. The young will snuggle into the mud about 1cm.

Although the clam maturation process is very risky, but with a large number of eggs, clam species have now become quite easy and inexpensive pets. Few people can believe that this 4-century-old clam becomes a pet that brings high economic value to Vietnamese and many fishermen in the world.
