When you hear about the legend of the oyster, you may picture a large red, button-shaped object in the ocean being slowly eaten by a mysterious stranger. This image is quickly put to rest, however, once you learn that the oyster is alive! The reality is quite different. Once you have had the opportunity to enjoy these delicious pearls, you may want to learn more about how they are kept healthy and vibrant.
Before you can consider how oysters live, it is important to understand how they get their shells. The oyster uses a special organ called a bivalve, which is tiny fingerlike appendages that attach to the oyster’s shell. The bivalve allows the oyster to “go to work” and creates a barrier between itself and whatever it is trying to protect. That is how an oyster protects itself from intruders or predators.
It is possible for a pearl to be “dead” for up to six hours before you can even get a real good look at it. This is because the oyster will remove the bivalve and regenerate it again. In the meantime, the oyster will fill the cavity with calcium carbonate. This process of renewal will keep the oyster growing until it hatches.
After the first cycle of growth has come to an end, the oyster will close its shell. It will then attempt to stop the flow of calcium carbonate. If it succeeds, the oyster will be trapped. If it is unable to trap itself, it will try to open the shell of the oyster again. This is why it is called a closed-door trap.
Of course, no oyster is going to remain alive if it is left out in the open. If you are thinking about eating a fresh pear, you may find yourself wondering, “Are oysters live when you eat them?” To answer this question, you should know that a pearl will only be a pearl if it has not been affected by any kind of parasitical agent. The only organisms that are capable of invading an oyster are bacteria and parasites.
Since they do not have any living cells, they are really only skeletons. If the oyster is kept alive for too long, however, it will start to die. This can happen because of a variety of reasons, such as overfishing, shock from harvesting, rough handling, water conditions, and more. If you want to eat an oyster that is still alive, you will have to keep it carefully handled until it is ready to be eaten.
Since the organisms that live in an oyster are slow-moving, it takes them a very long time to become old enough to die. For example, just two or three days is the average life span of a grain of sand. Even microorganisms, such as bacteria and other parasites, have a much longer lifespan than that. It may seem hard to believe, but a grain of sand can live for up to four hundred years, while an oyster only survives for a few years. Of course, this depends on the species of oyster.
There are other important factors to consider when you are wondering, “are oysters alive when you eat them?” For instance, an oyster that has been stored at room temperature will not always live. In order to preserve its tissue, it will have to be brought back to a warmer place. If you want to eat fresh oysters, you will need to store them properly to ensure that they will stay alive for many years to come.
