What Are Sea Shells
What are seashells?
Seashells are found in the ocean, and they come in all shapes and sizes. They can be white, black, or striped with different patterns. Many things such as money, jewelry, art pieces, etc. are consist of seashells.
People use seashells to make a picture frame. There is no wrong way to find a use for these beautiful little treasures that we see at the beach.
1. How are seashells made?
The ocean makes seashells. The world's oceans are vast and deep, which is why they produce so many stunning treasures.
Various living organisms create seashells, including clams, oysters, sea urchins, starfish, and coral polyps that live on or near shore. These creatures secrete calcium carbonate to form their shells which grow over time as they live in their environment.
When these animals die, their hard outer shell remains intact and becomes an object for new life to thrive in - whether another animal or plant species such as algae growing on top of it.
2. What are seashells made of?
Seashells are different, but how many of us have ever really looked closely at them? The shell consists of two layers. The outer layer (the periostracum) contains calcium carbonate and protects the inner one (the nacre).
Nacre provides a protective coating for small prey items such as urchins and clams while they're being digested in a gastropod's stomach.
3. Where do seashells come from?
Seashells are found in the ocean and formed from several animals, but they most commonly come from seashell-bearing mollusks such as clams and oysters.
A seashell is the hard, outer shell of a sea creature that lives in water, and some live on land too, but they are often live at the beach or shallow water near shorelines.
There are many different types of shells found worldwide, and each one has its own story to tell about where it came from.
4. What is unique about seashells?
Seashells live in the sea and sometimes on the shore. A seashore is a special place for shellfish to live. Here are some seashell facts:
i. Seashells are the exoskeletons of marine invertebrates.
ii. Seashells are made of calcium carbonate, which is the same material as pearls and limestone.
iii. There are about 1 million species of mollusks living today and around 100,000 different types of seashells.
iv. Some people believe that shells can bring them luck or protection from evil spirits.
v. A pearl is formed when an irritant gets inside an oyster's shell and causes it to produce nacre (a form of mother-of-pearl) to cover up the irritation.
vi. Shellfish like clams, mussels, and scallops all have two shells - one where they live and another to keep their body safe while they're growing inside their shell.
The world is a beautiful place, and there are many natural wonders to explore. Seashells, as well as the other treasures you can find on any beach walk, create a sense of wonder that will never fade away.
