Pseudococculinidae

Pseudococculinidae is a family of small sea snails or false limpets, marine gastropod mollusks in the superfamily Lepetelloidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

This family has no subfamilies. The species in this family are hermaphroditic. They can be found from sublittoral to hadal  depths.

Description
The shells are small (less than 6 mm), thin and translucent. The protoconch shows a  long, narrow apical fold. Its microscopic sculpture is smooth with fine threads. The asymmetrical radula shows a broad, rachidian tooth that lacks a cusp, four inner lateral teeth, a large  pluricuspid tooth, and numerous marginal teeth.

Soft body: the right tentacle is generally modified into a copulatory organ.
