Cephalopods
A cephalopod is a mollusk and an invertebrate; it has no skeleton neither external nor internal.
Every mollusk except slugs, which have evolved to not need a shell, has a shell. Snails, clams and other bivalves have an external shell. Octopi, squid and cuttlefish have an internal shell.
The visceral mass is the collective term for the non-muscular portions of a mollusc's body containing the internal organs.

A rock is not a mollusk
The member of the mollusk class that has an internal plate instead of a shell is the squid, specifically within the subclass Cephalopoda. Squids possess a structure called the pen, which is a thin, elongated internal remnant of a shell. This adaptation allows for greater flexibility and streamlined movement in the water, aiding in their predatory lifestyle. Other cephalopods, like octopuses and cuttlefish, also exhibit similar adaptations.
Every mollusk has a head, a body, and a foot. The head typically contains sensory organs and a mouth, while the body houses the internal organs. The foot is a muscular structure used for movement and can vary in shape and function among different mollusk species. Additionally, many mollusks have a protective shell made of calcium carbonate.
