Where do oysters live

The oyster (scientific name: Ostrea gigas tnunb) is a bivalve of the order Pinctada, mainly found in temperate tropical waters. It is one of the most resilient aquatic animals, with the shell adhering to other objects to solidify; to the ocean micro-algae and organic debris for food. Its shell is formed by the secretion of the outer coat membrane, which extends from the top of the shell to the ventral edge, and is a membrane formed by two layers of epithelial cells with connective tissue in between, with muscle fibers inside the membrane to keep it attached to the inner surface of the shell, and the edges of the outer coat membrane are thickened to form three pleats, and there are radial and circular muscles on the inner pleats to keep the edges tightly attached to the shell.

Habits

Adherent life

Adhering to other objects with the shell. [1] It is generally found in the intertidal and subtidal zones in water depths of up to 10 meters. [3]

Resistance

The oyster is also one of the most resilient aquatic animals. 200 million years of changing intertidal environments have created the oyster's ability to withstand temperature, salinity, open air, and common pathogens of the sea, and it is able to tolerate hot and dry weather in the summer when exposed to the surface of the water during the low tide and successfully adapt to the frozen weather in the winter, and it can survive for 1~2 weeks or even 1 month in the open air conditions. 2 weeks or even 1 month. [3]

Sex reversal

In natural populations, most individual oysters are dioecious, with a small number of hermaphrodites, and oysters can spontaneously "change sex", with the same individual showing different sexes in different years or under different environmental conditions. [3]

Food predation

Filtering for food. [1]Relies on microscopic algae and organic detritus in the ocean for its diet. [3]

Range

Oyster

Global distribution. China is rich in oyster resources and is the homeland of oysters, possessing a long history of utilizing oysters. As early as two thousand years ago, residents of some areas along the coast of southern China mastered oyster cultivation techniques. At present, there are oyster production bases in the Bohai Sea, Yellow Sea, East China Sea and South China Sea, and the main production areas are Fujian, Guangdong, Shandong, Guangxi, Liaoning and Zhejiang. Among them, the long oyster is the most important culture species.
