Oyster, as a high-quality mariculture shellfish, not only has the edible value of delicious meat, but also its meat and shell can be used as medicine, which has high medicinal value.

The shell can be divided into three layers on the cross section; the outermost layer is a thin and transparent stratum corneum, the thickest in the middle layer is a columnar structure composed of calcium carbonate called the prism layer, and the inner layer is a sheet-like structure of calcium carbonate called the nacre layer. The shell is formed by the secretion of the lower mantle. The mantle extends from the top of the shell to the ventral edge. It is a membrane formed by two layers of epithelial cells with connective tissue sandwiched between them. There are muscle fibers in the membrane to attach it to the inner surface of the shell. The edges of the membrane are thickened to form three folds, and the inner folds have radiating muscles and circular muscles to make the edges close to the shell. There are a large number of sensory cells or sensory organs on the middle folds, which have functions such as touch and vision. Outer folds have a strong secretory function. 

The two shells are not equal, the left shell or lower shell is larger and concave, and the left shell is fixed on the rock or seabed stake. Generally, in the late stage of metamorphosis of the face plate larva, mucus is secreted by the foot silk, and the mantle edge is fixed to the substrate, and then the shell secreted by the mantle is directly attached to the plug substance. The foot completely disappeared, the anterior adductor muscle also degenerated and disappeared, and the posterior adductor muscle moved to the middle of the body, completely losing the ability to exercise. The adductor muscle and ligament have an antagonistic effect. Due to the permanent fixation life, developed small tentacles or sense organs appear on the periphery of the mantle, and the mantle never shows healing points or forming water pipes, because they live on hard surfaces, where there is rarely a large amount of sediment, due to tidal movement Has played a clear role.
