Exoskeleton of Mollusks
Like crabs and other marine animals, their skeletons grow outside. Thus, this serves as a protective layer from predators. The hard substance protects the body inside, and they also come in various shapes and sizes. There’s research showing majority shells open to the right, 9 out of 10 shells do. And shells’ opening to the left is rare.
Mollusks produce calcium carbonate, turning them into shells, and they spend most of their lives underwater and absorb the minerals of the sea. Their unique bodies can process these minerals. Minerals aid in forming the shells, and they are not from mollusk cells. Hence, the organism is separated from the structure. When they die, the shells will continue to grow. Shells have the same proteins found in human fingernails. Living in tropical parts has more food sources. So they can generate attractive shells. These shells are also durable.
