Some of it is a little technical, but it does a great job describing all types of seashell structures.
On beaches and near the sea. I have also found some on the shores of lakes.
The person who studing about the shell is calles as chonchologist.

No, the calcium the earth has is all it will have. It is not renewable. Most of the calcium available is in fossil form (e.g. ancient coral reefs, deposits of seashells, organic ooze) that will take millions of years to be replaced (like coal, petroleum, and natural gas). However it is easy to use calcium from bones and seashells harvested today.
Shells naturally start to lose color when the animal inside is gone. Exposing them to light will often cause the colors to fade faster. Seashell collectors keep their collections in cabinets or display cases that are dark until opened for viewing.
Seashells are, quite simply, the exoskeletons of mollusks. At Britannica.com, you can learn a good deal about the composition of seashells, including the three distinct substances involved: an outer layer of the horny substance conchiolin, an intermediate layer of calcite, and a smooth inner layer composed mainly of calcium carbonate.But how does a mollusk actually create a shell? An article from Earth & Sky explains:The blood of a mollusk is rich in a liquid form of calcium. A soft, outer organ called the mantle concentrates the calcium in areas where it can separate out from the blood, forming calcium carbonate crystals. The mantle deposits sheets of the crystal in varying thicknesses. The individual crystals in each layer vary in shape and orientation.A facinating new field called biomimicry, which attempts to replicate Nature's materials, has recently generated detailed studies of abalone and conch shells in an attempt to understand the source of their amazing toughness and strength. This knowledge could be used to create unbreakable windshields and other scientific marvels.Largely Calcium Carbonate.scientific marvels.

Seashells
Seashells, sand, water,
Yes, you can keep seashells you find on the beach and you don't need a permit to collect items on a beach.
Not necessarily. While nearly all fossils, including seashells, are found in sedimentary rock, most sedimentary rock does not contain fossils. Even then, those fossils will not necessarily be seashells. If you do find a rock with seashells, though, you can be pretty much guaranteed that it is sedimentary.
Yes, in some deserts one may find fossilized seashells. Some deserts also occur along a coastline and shells could be found there, also.
You can find seashells on the sea shore.
Limestone.
That would be seashells.
The correct spelling is seashells. An example sentence would be "there are plenty of seashells on the beach".
No whales do not grow with seashells
There is no such thing as seashells language.
