Oysters and oysters are two completely different foods, although "oysters" are often called oysters in many places, or strictly speaking, oysters belong to one kind of oysters.
Oyster is a mollusk with two shells, one is small and flat, the other is large and bulging, triangular, and the back and abdomen edges are splayed. The outer surface of the right shell is light yellow, the concentric scales are loose, the scales are undulating, and the surface of the inner white shell is uneven. Meat can be eaten and oyster sauce can be made. Meat, shell and oil can be used as medicine. Also known as oyster clam, oyster clam, oyster yellow, oyster, oyster and so on. There are many kinds of oysters living in different sea areas.
Oyster is one of the larger oyster varieties, and a big oyster with a shell can weigh more than one catty. Generally, it grows or is cultivated in the place where rivers and the sea blend, on the shallow sea in the inner bay, half salty and half light. Due to the restriction of suitable growth conditions, its quantity is less than other varieties, so its economic price is generally higher.
