In mollusks, the columella is a central, supporting structure within the shell, particularly in gastropods and some bivalves. It serves as an anchor for the shell's whorls and provides structural integrity, allowing for the shell's coiled or spiral shape. The columella also plays a role in the attachment of the soft body of the mollusk to the shell, aiding in the organism's overall stability and protection.
