The hard shell protects the very soft body of the mollusk.
Mullucks, commonly known as mollusks, do not have a backbone. They are a diverse group of invertebrates that includes animals like snails, clams, and octopuses. Instead of a backbone, mollusks typically have a soft body and may possess a hard shell for protection. Their body structure is quite different from that of vertebrates, which do have backbones.
I assume calm means clam? In which case, a clam does have a hard external (skeleton?) shell of calcium carbonate. The shell is known as an exoskeleton.
A crab has an external hard shell, and is an invertebrate.

The main function of the Ethernet external hard drive is to connect the internet between the modem and the computer. To be able to connect internet, you need an Ethernet cable.
Mollusks do not have an external skeleton; instead, they have a hard, protective shell made primarily of calcium carbonate. This shell serves as a form of defense and support. In some mollusk species, such as octopuses and squids, the shell is reduced or absent, but the mantle tissue still secretes the shell material when present.
