Oyster: It's a kind of seafood shell. Suitable for oyster culture in subtropical and tropical coastal areas, widely distributed in China. Oysters can be produced from the Yalu River in the north to the coast of Hainan Island in the south. Oysters are soft-shelled parasitic animals, especially those produced in the freshwater border of Yu Xian.

Oysters are mollusks. They have two shells, one is small and flat, the other is big and bulging, and the surface of the shell is uneven. Meat can be eaten and oyster sauce can be made. Meat, shell and oil can be used as medicine, also called oysters or oysters.

Since 2000 BC, oysters have been cultivated as food; Pearls can be produced in the shell of pearl oyster.

The two shells of oysters are different in shape, and the surface is rough and dark gray; The middle part of the upper shell protrudes; The lower shell is attached to other objects, with large volume, quite flat and smooth edges; The inner surfaces of both shells are white and smooth.

The two shells are connected at the narrower end by an elastic ligament.

There is a powerful adductor muscle in the middle of the shell to resist the tension of the ligament. When the shell is slightly opened, water flow is introduced into the shell through the wave-like movement of cilia, and microorganisms are filtered. Oysters are mostly hermaphroditic, but some are hermaphroditic.

Oysters breed in summer. Some kinds of eggs are fertilized in water, while others are fertilized in females. The hatched larvae are spherical and ciliated, and are permanently fixed to other objects after swimming for several days. Harvest after 3 ~ 5 years.
