Caecidae is a taxonomic family of very small and minute sea snails or micromolluscs, marine gastropod molluscs in the order Littorinimorpha.

hell description

The shells have discoidal nuclear whorls which are shed soon after the adult stage commences. The adult stage is in the form of a simple, slightly curved, tube, which is sealed off at the narrow end by a blunt rounded septum. The aperture of the shell 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.

This family contains three subfamilies :
* Caecinae Gray, 1850
* Ctiloceratinae Iredale & Laseron, 1957
* Strebloceratinae Bandel, 1996

Genera

* "Caecum" Fleming, 1813
* "Fartulum" Carpenter, 1857
* "Micranellum"
