Gastropoda Classification


The following taxonomic table is that of Poppe & Tagaro (2006) for marine shell organisms in the Prosobranchia and Opisthobranchia subclasses. It is based on Bouchet & Rocroi's gastropod classification update (Bouchet & Rocroi, 2005), but abridged to exclude fossil species. In this table, the clades reflect major revisions based on DNA and RNA molecular studies, more detailed soft tissue anatomy, and other current advances. There are many significant changes from the traditional Linnaean taxonomic classification.
