What is the difference between sponges and the sponges we use?

Does a non-moving animal, a sponge that grows in the sea, and sponge technology products that we use every day have the same properties?

In general, animals should be able to move freely, but the sponge is one animal that doesn't.

A cartoon character such as SpongeBob is alive and well. It's just a cartoon. Although the real SpongeBob is an animal, it cannot move.

How does this sponge relate to the sponges we use every day in chairs, sofas, mattresses, car cushions, bath foam balls, etc.? It does.

Sponge use on a daily basis

Over 400 million years before dinosaurs, sponges lived in the oceans during the late Proterozoic and early Paleozoic, about 600 million years ago. There are no organs or hands or feet in sponges, so they cannot actively feed or move. They can only stay where they are and can't move at all. They are the simplest multicellular animal.

They eat through their mouths.

The use of water flow can bring food and oxygen, but if there is no water flow stationary, sponge cities have to develop to avoid starvation and suffocation. Water flows inside and out of sponge animals through their many small holes, which are connected to the pipeline system. Water flows into and out of sponge animals, bringing oxygen and food, but also waste away.

Don't look at the sponge's head, we're not big, but it's the throughput of China's seawater is quite astonishing. Every day, you can flow through a mass of water that is thousands of times larger than the culture of the sponge. Often, people describe schoolboys to the knowledge of the absorption of a great deal by describing the sponge as sucking up water.

Since the sponge has been around for a long time, its recalcitrance has not changed in any way, and evolution has not progressed. As a result, its position in the classification of animals has been relegated to a blind branch, a side branch, so to speak, hence the name "parazoan".

It was treated as a plant for a long time

There are only a few sponge species that live in fresh water, often attached to rocks, shellfish, algae, and other objects. Most live in tropical and subtropical oceans, from shallow coastal waters to oceans up to 7 kilometers deep. In the past, sponges were thought to be plants, and it wasn't until the 19th century that zoologists realized they belonged to animals.

Small animals' home

It is known as an animal for its calm, quiet development, and the fact that it doesn't attack others, and it is not liked by others. As a consequence, we do not have social conflicts with any other animals, and small animals love it, and small fish and shrimp can often hide in the sponge, like family.

They like sponges called "flower baskets". When they are young, they hide in pairs in the holes of the sponge. When they grow up, their bodies are too big to come out, so they just live in their holes without shame.

A remarkable ability to regenerate

As a general rule, lower animals have strong regenerative abilities, and sponges are no exception. When a sponge is cut into small pieces, it doesn't threaten its survival, but each piece grows into a new sponge independently. It takes just a few days for them to re-form into individual sponges even if they are mashed up.

As a result of its many benefits, natural sponges have become one of the most popular varieties for humans. Since it is a bath, it is related to bathing, because its skeleton is a soft sponge silk, elastic, and super absorbent, used for scrubbing the bath that is an ultimate pleasure. As well as being used to bathe, it is also used to clean the wound and absorb blood.

Sponge products we usually use are almost always made from chemical porous elastic materials derived from foam polymers, which have nothing in common with natural sponges.

In cushions, sofas, mattresses, etc., chemical sponges are used, bathing and dishwashing also require chemical sponges, so students imitate sponge water absorption and manufacture elasticity characteristics.

European countries sell natural sponges

Despite the fact that natural sponges are more than ten times more expensive than chemical sponges, chemical sponges cost a few dollars while natural sponges can cost tens of dollars.

Natural sponges that are dry

High-end bath sponges are usually made from natural sponges because of their high price.

In addition to the Mediterranean Sea, bath sponges are also found in China and Japan, although in much smaller quantities.

Bone sponge filaments are composed of natural keratin, and the skin-friendly feel is completely different from chemical materials.
