"Caecum" is a genus of minute sea snails, marine gastropod molluscs or micromollusks in the family Caecidae.

hell description

The shells have discoidal nuclear whorls that are shed soon after the adult stage commences, which is in the form of a simple slightly curved tube, now sealed off above by a blunt rounded septum. The aperture is circular and so is the tight fitting operculum.

Life habits

The animal grazes upon filmy organic deposits, and moves about jerkily by advancing the foot and then dragging the shell in a series of short steps.
