Description

Coralliophila nodosa is a medium-sized marine gastropod, recognized by its robust, nodulose shell. The exterior typically presents a variable coloration, ranging from whitish, cream, or pale pink to purplish, sometimes with darker bands. A distinctive feature is its wide, ovate aperture, which often displays a striking vibrant pink or purplish-pink interior. The shell is characterized by prominent axial ribs that frequently develop into distinct nodules or tubercles, particularly on the shoulder of the whorls. This species is a specialized predator of stony corals, inhabiting coral reef environments across tropical and subtropical waters.
