Caecidae is a taxonomic family of minute sea snails or micromolluscs, marine gastropod molluscs in the order Littorinimorpha.[1]
Habitat
[edit]These minute tubular shells can be found living in marine sediment, or among algae or sponges, in warm and temperate seas.
Shell description
[edit]The shells in this family are unusual in that the adult shell is a curving tube. In the subfamily Caecinae the protoconch is lost, and the tube is sealed with a permanent calcareous plug at one end. In the subfamilies Ctiloceratinae and Strebloceratinae the protoconch is retained. At the other end, the tube is sealed by a circular operculum. The spiral part is almost always lost when outgrowing the juvenile stage. The color of the shell is white to pale yellow.
Taxonomy
[edit]This family contains three subfamilies:
- Caecinae Gray, 1850
- Ctiloceratinae Iredale & Laseron, 1957
- Strebloceratinae Bandel, 1996
