Difference between oysters and oysters: different morphology, different taste, different distribution. Pictures are as follows:

1, different forms

The difference is obvious, oysters are bigger than oysters, larger oysters with shells can be more than a catty, can be said to be a giant, and oysters are only about 2 two, the difference in size is very big. The price of oysters and abalone, the larger the more expensive, more than a catty of oysters are sold by the individual. And oysters are weighed by the pound.

2, taste different

Oysters are large, so it is more meat than oysters, eat more thick and full, taste better, but oysters are not so much meat, not as good as oysters.

3, the distribution of different

Oysters are generally distributed in the intertidal zone, as well as the subtidal zone of the water depth of not more than 10 meters of the sea, while the current culture of oysters generally live in the sea area in the depth of more than 8m of seawater, especially in the cold, salty seawater, the more delicious flavor. And oysters also have natural, artificial culture of 2 kinds, but are distributed in the river and the sea at the confluence, half-salty, half-fresh shallow bend, the environment is restricted, so the number of oysters than oysters less, the price is naturally more expensive than oysters.

Morphological Characteristics of Oysters

The shell can be divided into three layers in section; the outermost layer is a thin and transparent cuticle, the thickest middle layer is a columnar structure of calcium carbonate called prismatic layer, and the inner layer is a lamellar structure of calcium carbonate called pearl layer.

The shell is formed by the secretion of the coat membrane below, the coat membrane extends from the top of the shell to the ventral edge, it is two layers of epithelial cells, sandwiched between the connective tissue formed by the membrane, the membrane has muscle fibers to make it attached to the inner surface of the shell, the edge of the coat membrane is thickened to form three pleats, the inner pleats have radial muscles and circular muscles to make the edge of the shell close to the shell. The middle pleat has a large number of sensory cells or sensory organs with functions such as touch and vision. The outer fold has a strong secretory function.
