No, kitchen sponges nowadays are usually made from cellulose or synthetic plastics. Real marine sponges were used by early Europeans to also clean, but it was stopped due to overfishing that almost brought the sponges to extinction.
No, barrel sponges do not migrate. They are sessile organisms, meaning they are permanently attached to a surface and do not move from one place to another. Barrel sponges rely on water currents to bring them food and oxygen.
Sponges are aquatic animals that live in freshwater or marine environments. They can be found attached to rocks, reefs, or other hard surfaces on the ocean floor. Sponges are filter feeders, meaning they pump water through their bodies to collect food particles.
Sponges are Eukaryotic. They are multicellular, and their cells contain membrane-bound organelles.

Because we wanted to call them sponges. Sponges belong to the animal kingdom since they are heterotrophic. Fungi derive food from breaking doown orgainc material in soil. Sponges feed on existing material. This is the difference.
sponges have a large amount of air spaces in between them. When we squeeze them, the air is expelled out & after releasing the pressure the air reenters helping it to regain its original shape. The presence of air spaces make sponges compressible.
