Hydrocenidae

According to one version of gastropod taxonomy, Hydrocenoidea is a superfamily of small snails, gastropod mollusks. This superfamily contains the family Hydrocenidae, the cave snails.

These snails are within the order Neritoida, the nerites and their allies.

Please see the article Hydrocenidae for more information.

(Note: Gastropod taxonomy has been in flux for more than half a century, and this is especially true currently, because of new research in molecular phylogeny. Because of all the on-going changes, different reliable sources can yield very different classifications. This is especially true within groups which are poorly understood in general.)
