A tortoise or turtle.
A sea shell may contain a dead animal but the shell itself is a protective covering that an animal made to protect itself.

Hermit Crab, turtle, and clam fit this analogy.
Reptiles have a body covering of dry, scaly skin. They do not have individual scales as fish do, but the scales (also known as scutes) are joined together to form a seamless outer covering of skin. The scales are made of keratin, the same substance of which human fingernails and hair are made.
protective shell in marine foraminiferans
The lower shell of a turtle is called the plastron. It is the protective structure on the underside of the turtle's body, composed of bone and cartilage, and helps provide support and protection for the animal's vital organs.
Turtles are reptiles, not mammals. They belong to the order Testudines and are known for their protective shell and slow movements on land.
shell
Members of the class Aplacophora are mollusks that have an internal plate instead of a shell. Aplacophorans lack a protective shell but possess calcareous spicules or scales in their skin. These marine mollusks are often found in deep sea environments.
it is difficult to remove the scales. we cannot use scale forming fluid through the shell because if we pass, the scales are formed and it corrodes the shell.
The snail can protect itself by, when threatened, retracting into its shell and therefore hiding beneath their protective shell.
