No. oysters do not have an advance neurological system.
No. Natural pearls grow in pearl oysters deep underwater, where not much sunlight can usually reach them. What initiates pearl growth is when an irritant infiltrates the shell of an oyster, and the oyster secrets nacre to coat the irritant and protect its soft flesh. There's a lot of good information on pearls at the link below.
Mother-of-Pearl is found in Oyster shells
It is quite rare for two pearls to form in a single oyster shell. Most oysters produce only one pearl at a time, as the process of pearl formation involves the oyster secreting layers of nacre around an irritant. While there are exceptional cases where two pearls can develop, they are not common, and the occurrence can depend on various factors, including the species of oyster and environmental conditions. Overall, the production of two pearls in one shell is an unusual phenomenon.
Pearl is produced by an oyster to protect itself from something that got inside its shell. It secretes nacre, which becomes pearl. Cultured pearls are made by placing a "seed" inside of the oyster shell, and letting the oyster work. Over time, the oyster will deposit nacre onto the seed, forming a pearl.
They can be found almost any shelled mollusk such as the pearl oyster
No. Pearls are a byproduct of sand getting into the mouth of the oyster, and the oyster wrapping mother-of-pearl cells from it's body around the sand grain to decrease the irritation from the grain of sand.
In fact every clam, not just the oyster, can make pearls. Pearls are made because of a tiny bit of dirt, sand or whatever, comes inside the clam. The clam then makes 'mother-of-pearl' which is a substance that makes a pearl after a pretty long time.
Pearls are 'grown' by some irritant entering an oyster and the oyster growing a layer of mother-of-pearl (nacre) around it. In natural pearls this is usually a grain of sand and it takes a lot of growing to get a pearl of marketable value. Artificial (cultured) pearls are made by people inserting some round object (the size and shape of the desired pearl) and letting the oyster grow a thin layer of mother-of-pearl around it. This object can be anything but shell or porcelain are preferred as they do not break down. If one uses wood then, over time, the wood will eventually rot and the 'pearl' will fall apart. Such pearls are not valuable and are considered a scam. The only way to tell real pearls from artificial pearls is by using an x-ray machine however it is still difficult to tell what the centre object is made of.
Pearls are usually from oysters. Most pearls today are cultured pearls, meaning that they are specially done. What they do is to put an irritation into the oyster shell so that the oyster can make a pearl. A pearl is really just kind of a "tumor" thingie. The oyster can't get rid of some irritants like sand or grit, so it will deposit something called nacre over the thing that is bugging it. Over time, this will become a real pearl and it's size depends on how long the oyster has to coat the thing. The reason it's called a cultured pearl is that man will put the "dirt" in the pearl rather than it happening naturally. So after the pearl has been taken from the oyster, jewelers will mount it on an earring mounting. These mountings are usually precious metal, and the price of the earrings depends on the quality of the pearl, the shape of the pearl, and the quality of the earring mounting.
The pearls sold at Epcot, specifically in the Japan Pavilion, are typically cultured pearls rather than natural pearls. Visitors can participate in the "Pearl Oasis" experience, where they can select an oyster to open and reveal a pearl inside. While these pearls are real in the sense that they are genuine cultured pearls, they are not as rare or valuable as natural pearls found in the wild.
A pearl is made up of calcium carbonate in minute crystalline form, which has been deposited in concentric layers. The pearl comes from the oyster.
A natural pearl when rubbed gently on your teeth will be "grity" while a cultered pearl will be smooth. == == That is not true. Both Natural and Cultured Pearls will be grity when rubbed gently on your teeth.
