Virginia State Shell

Oyster Shell

Virginia State Shell: Oyster Shell

(Crassostrea virginica)

Adopted on March 5, 1974.

On March 5, 1974, Virginia adopted the most popular of state shells, the eastern oyster, (Crassostrea virginica,) which also represents Connecticut and Mississippi.

Several Virginia Beach school children carrying oyster shells gathered around Governor Mills E. Godwin Jr. as he signed the oyster into law. One girl presented Godwin with a shiny oyster shell, and he said, "I come from down in oyster country, you know."

A school group came up with the idea of adopting the oyster which was introduced in the legislature by Owen B.Pickett of Virginia Beach. Pickett thought an official oyster might help promote tourism.

Virginia's oyster capital is the Menchville area. It is located in southern Virginia on the James River, the largest natural seed oyster bed in the Chesapeake Bay area. In winter, boats from all over to Virginia coast gather at Menchville to work on the public seed beds. Boats from Maryland and northern Virginia also visit Menchville to buy seed oysters, which they plant in the upper Chesapeake Bay and in rivers.

Virginia even has an official boat to harvest oysters from, the Chesapeake Bay deadrise!

The Eastern oyster is relatively large, growing up to 10 cm. in length. It is normally somewhat pear-shaped in outline, but members of this species vary greatly in size and shape. The shell is dirty gray externally and white internally, except for the muscle scar, which is deep purple. Oysters usually colonize in beds. Competition for space is a most important source of mortality. Uncrowded, oysters can live to be 20 years old. The beds are a permanent social structure unless they are separated physically and forcefully. Otherwise, the oysters will re-congregate if they are capable.

Shell

Oyster shells are made of calcium carbonate (lime). The oysters must get this lime from the water they live in. They also have a sort of skin, called a mantle, which puts this calcium carbonate on the outside of their bodies to form a protective shell. Oysters must live in water that is temperate (warm all year) and not too cloudy. They grow only in areas where salt and fresh water mix together, like salt marshes. Oysters are born as free-swimming plankton (tiny microscopic organisms). When they grow up, they find a place (on mud, coral, debris, or other oyster shells) to attach and grow. Once they grow their shells, they can't move around anymore. When the tide is high, oysters are covered by water, but when the tide goes out, they are left sticking up into the dry air. Their shells close tightly together so the animal inside will not dehydrate (dry out) before the tide comes back in.

Diet

After spawning in early spring, the oyster loses a great deal of weight. This event usually coincides with the spring bloom of phytoplankton, their primary food source. Feeding is dependent upon water temperature; more food is consumed at higher temperatures than at lower. Oysters are filter-feeders. They suck in water and filter out the plankton and detritus to swallow. Then they spit the water back out. (Detritus is dead plant and animal matter.)

Reproduction

Reproductive organs can be readily observed only during the breeding season. There is no reproductive activity during the winter. Sexual maturity is a function of size rather than age. The first spawning usually occurs when the oyster is 2 years of age. Fertilization occurs when huge numbers of sperm sperm and eggs are expelled from the male or female and meet in the water.

Pearls

The oyster's mantle (skin) makes both an outer white crusty shell, and a smooth inner shell. The smooth inner part is called "nacre" or "Mother of Pearl." Sometimes a bit of sand gets inside the oyster's shell. This is very irritating to the oyster, like getting an eyelash in your eye. So the oyster covers this bit of dirt with shiny smooth Mother of Pearl. It keeps covering the dirt and rolling it around until it doesn't cause any more irritation. This makes a pearl. The oysters that people eat in north Florida (Eastern oysters) hardly ever make pretty pearls. But there are other kinds of oysters, clams, mussels, conchs, whelks, and even abalone that do make nice pearls. We think of pearls as being round and white, but they are often yellow or black, and many other colors and shapes.

The law designating oyster shell as the official Virginia state shell is found in the Code of Virginia, Title 1, Chapter 5, Section 1-510. Virginia symbols were re-organized under one section of the Code of Virginia in 2005.

State Shells
State Shells
A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer created by an animal that lives in the sea. The shell is part of the body of the animal. Empty seashells are often found washed up on beaches by beachcombers. The shells are empty because the animal has died and the soft parts have been eaten by another animal or have rotted out.
