Seashells are a living thing when connected to the snail because its the snails calcium that grows and develops but when the snail dies the shell dies so therefore the seashell is not a living thing because it is dead.

Are seashells minerals?

Seashells are the exoskeletons of mollusks such as snails, clams, oysters and many others. Such shells have three distinct layers and are composed mostly of calcium carbonate with only a small quantity of protein–no more than 2 percent. Think of laying down steel (protein) and pouring concrete (mineral) over it.

How is a seashell made?

“A seashell is a protective outer coating secreted by the animal’s mantle, which is one of their muscles,” she said. The mantle forms the soft outer wall of their body. A mollusk produces calcium carbonate from its mantle, laying down layers of it over its lifetime. Together, those layers form the seashell.

Are Sand Dollars alive?

While the sand dollars are still alive when stranded, they are unable to make it back to the water once the tide recedes. Instead, they are drying up and dying.
