Gastropod classification

This overview lists proposed changes in the taxonomy of gastropods at the family level and above. There have been many changes in the way various groups of snails and slugs are classified.

Changes in subfamilies are outlined in the respective articles about each particular family. Unchanged taxa are not listed here.

In one of the largest recent changes (affecting the most species of gastropods), Klussmann-Kolb et al. (2008) showed that the traditional classification of the Euthyneura needed to be reconsidered. The change was subsequently made by Jörger et al. (2010), who redefined the major groups within the Heterobranchia.

A great number of major changes have been made within the classification of the Conoidea since 2011.
