oyster,

bivalvebivalve,
aquatic mollusk of the class Pelecypoda ("hatchet-foot") or Bivalvia, with a laterally compressed body and a shell consisting of two valves, or movable pieces, hinged by an elastic ligament.

 mollusk found in beds in shallow, warm waters of all oceans. The shell is made up of two valves, the upper one flat and the lower convex, with variable outlines and a rough outer surface. Since the wild oyster spends most of its life (except for the free-swimming larval stage) attached—having fused its valve with a sticky substance to a substratum of shells, rocks, or roots—the foot is rudimentary.

In some species the sexes are separate and the eggs are laid and fertilized in the water; in others the animal is hermaphroditic and the eggs are retained with the shell. Only a small proportion of the millions of eggs laid survive. Large numbers of the free-swimming larvae, called veligers, are consumed by fish and other animals. After the oyster becomes sessile, it may be victimized by oyster drills, starfish, and other enemies.

Edible oysters belong to the family Ostreidae, the true oysters. The eastern oyster, Crassostrea virginica, reaches a length of 4 to 6 in. (10–15 cm). These oysters are harvested in artificial beds on both coasts of the United States: on the Atlantic especially in the regions of the Delaware and Chesapeake bays and in the waters off Long Island, in the Gulf Coast off Louisiana, and in the Pacific off the state of Washington. Prepared beds are usually seeded with veligers or young sessile oysters called spats. In warm waters they mature in 1 1-2 years; in cooler waters the period of growth is about 4 to 5 years. They are usually transplanted several times before harvest to enhance their food supply and stimulate growth. Oysters are also farmed in mesh cages, trays, and bags (which may have floats incorporated), on ropes to which they have been attached, or in special tanks. The Pacific oyster, C. gigas, native to the coast of Asia and farmed there, also is farmed in the U.S. Northwest, Europe, and Australia and New Zealand. The edible oysters of the genus Ostrea, such as the Belon and Olympia oysters, are less significant commercially than they once were, due to overharvesting and disease.

The wing and the pearl oysters, of the family Pteriidae, are widespread in warmer seas; there is one eastern and one western species of each in American waters. The great pearl oyster, from which the pearlpearl,

Oysters are classified in the phylum MolluscaMollusca

What does it mean when you dream about an oyster?

Symbolizing pearls of beauty, wealth, or wisdom, the oyster can also symbolize sexual arousal. In a dream the oyster may represent something of great value to be “shucked” in one’s waking hours.

Oyster

(dreams)
An oyster in your dream may have sexual connotations. It usually represents the female sex organ or, if eaten by a man, may represent his ability or desire to perform well sexually. Oysters are also considered symbols of humility and wisdom. Their meaning is associated with that of pearls. The most negative interpretation is that the oyster represents a well-guarded individual; a person who has shut himself off from others. Attempt to connect some of these ideas to your emotional life and overall experiences and keep in mind the setting, context, and outcome of the dream.
