What is the purpose of seashells?

Answer 1

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.

Answer 2

its a fossil found in the ocean.
A sea shell is a fossil or skeleton of a creature that lives in the ocean. The creature is born with a hard back and as it grows the shell will expand and begin to curl. The shell will protect the resident (slug or crab) untill it dies. When it dies the resident will eather rot or be eaten, leaving the shell behind. After the resident is gone the shell could be caught in a fishing net and taken away on a boat. Most of the time they are found on beaches.

Answer 3

It protects the Mollusk, can be used as a tool to move or open objects, adn can be used for camoflouge adn even sold in sores or collected.

to protect the creatures within them. otherwise, thiere isn't really a purpose. there just shells; parts of animals

Answer 4

well the shore line for one and in the ocean floor

Answer 5

seashells are important because seashells can help save us from global warning !

Answer 6

Mostly Calcium carbonate, and so seashells are an excellent CO2 sink, locking up carbon until it is subducted, one of the aims of Speybay mussel farm.

Answer 7

A seashell itself is not an animal, but what lives inside it is.
