coiled shell
Snail's curved home
A coiled shell is the spiral-shaped protective covering of certain mollusks, especially snails and nautiluses.
The shell grows in a logarithmic spiral as the animal adds material to the opening, creating the characteristic whorl pattern.
Coiled shells appear frequently in art and architecture as symbols of growth and natural geometry.
