Caecidae is a large family of very small or minute snails, marine gastropod molluscs in the order Sorbeoconcha.
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. 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.
