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
