Answer 2

1. Seashells are the hard, protective outer coverings of various marine animals, primarily mollusks and some crustaceans. These shells are made primarily of calcium carbonate and serve as a form of protection for the animal inside.

2. Mollusks have their skeletons inside their bodies, typically in the form of a soft, flexible structure called a "mantle." This mantle secretes calcium carbonate or other materials to create the hard shell that surrounds and protects the mollusk's body. The exact structure of the shell can vary among different mollusk species.

3. Crabs use shells primarily for protection. They do not create their own shells but instead rely on shells from other marine animals, particularly gastropod mollusks like snails. Crabs find empty shells, often ones that fit their size, and use them as a protective covering for their soft bodies. As the crab grows, it may need to find a larger shell to accommodate its increasing size.

4. People have created various art and decorative items from seashells for centuries. Some common creations from shells include jewelry, wind chimes, picture frames, and ornaments. Shells are also used in crafting and home decor, as they come in various shapes, sizes, and colors, making them versatile materials for creative projects.

5. People often keep a variety of items in shells for decorative or functional purposes. Some examples include using shells as small containers for jewelry, keys, or other small items. Large shells, such as conch shells, can be used as decorative pieces or even as musical instruments when blown into. Additionally, shells are sometimes used as serving dishes for appetizers or seafood presentations in culinary contexts.
