These sea snails live in rocky shores in the mid-eulittoral zone and deeper.[1]


Shells of Cerithium caeruleum can reach a length of 20–40 millimetres (0.79–1.57 in).[2] These shells show a few rows of nodules and tiny beads on whorls. The external surface of the shell may be brown, greyish-white or greenish, with a white aperture.[1]
