Cerithium caeruleum, the Cerith sand snail, is a species of sea snail, a marine gastropod mollusk in the family Cerithiidae.
This species is widespread in the tropical Indo-Pacific (Red Sea, Kenya, Madagascar, Mozambique, Tanzania and Western India).
These sea snails live in rocky shores in the mid-eulittoral zone and deeper.
Shells of Cerithium caeruleum can reach a length of 20–40 millimetres (0.79–1.57 in). 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.
