Pearls grow in pearl-producing mollusks. Natural pearls occur when a mollusk's mantle tissue becomes damaged either by parasitic intrusion or damage to the shell. The mantle contains epithelial cells, which are responsible for the nacre deposition on the inside of the shell. If these cells become dislodged when the mantle is damaged, they may continue to deposit nacre within the body of the mollusk, creating a pearl.
A grain of sand neverproduces a pearl. This is a myth.
If a grain of sand, or some other substance, gets inside an oyster's shell, its tissues will start forming layers and layers of mother-of-pearl around the grain of sand until it cannot feel the irritation any more
It doesn't.
The oyster makes a peal when a grain of sand gets trapped in its shell. The sand is covered layer by layer over the time it spends in the oyster until the oyster dies.
They make pearls
No
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.
No. Pearls can be many diffrent colors. The color depends on the type of clam that produces them.
Clams can form pearls!
The collective nouns for pearls are:a string of pearlsa rope of pearlsa cluster of pearls
Look in a clam. That's where pearls are made.
you put sand in it and wait for a long time
Sand never, ever creates a pearl. That theory is a myth.
Yes. It happens when a clam gets 1 grain of sand in its mouth, then the grain of sand turns into a pearl (but I don't know how! Sorry!). Then someone goes clam fishing or finds the clam and opens it up to get the pearl. Not all pearls are white. And not all clams have pearls in their mouths.There is also a process called culturing where a small piece of clam shell is placed inside an oyster's shell. To protect itself from the irritation caused the oyster coats it with th stuff pearls are made of and a pearl is made. The longer the pearl stays in, years, the bigger it gets. Most of the pearls around today are cultured.Yes it does but it is not made by sand. It is actually made by a parasite entering the clam and the clam coats it with nacre. Nacre is what a pearl is made of. Not sand.
pearls are made when a grain of sand gets trapped in a clam. then it eventually grows into a pearl. clams live in the sea, so yes salt water pearls exist.
the shell protects the clam from predators. The shell also helps make pearls when the clam has something that is irritating the clam. The irritating object has to have part of another clams mantle on it" it makes the pearl with the mother of pearl which is the shinny part on the inside of the clam.
