Are seashells a living thing?
The actual seashell is not living, it is a hard, protective outer layer made by an animal that lives in the sea. The shell is not part of the body and was never living. The common seashell is produced by a mollusc, and by the time the shell reaches the shore, the invertebrate has been eaten or rotted out, leaving the more durable exoskeleton - the seashell.

Crabs, shrimp, crayfish, and lobsters, are also arthropods and their hard shells are also an exoskeletons. In the group termed mollusks we also see animals with true hard shells, included in this category are snails, clams, scallops, oysters, tusk shells, chitons, nautilus, to name a few.
