Euthyneura is a taxonomic clade of snails and slugs, which includes species from the sea, the land and freshwater; marine, aquatic and terrestrial gastropod mollusks in the clade Heterobranchia.
Euthyneura are considered the crown group of Gastropoda. Euthyneura are characterised by several autapomorphies but are named for euthyneury. They are considered to be the most successful and diverse group of Gastropoda. Within this taxon Gastropoda have reached their peak in species richness and ecological diversity. This obvious evolutionary success can probably be attributed to several factors. Marine Opisthobranchia, e.g., have evolved several clades specialised on less utilised food resources such as sponges or cnidarians. A key innovation in the evolution of Pulmonata was the colonization of freshwater and terrestrial habitats.[2]
Various phylogenetic studies focused on Euthyneura: Dayrat et al. (2001),[3] Dayrat & Tillier (2002)[4] and Grande et al. (2004).[5] Morphological analyses by Dayrat and Tillier (2002)[4] demonstrated the need to explore new datasets in order to critically analyse the phylogeny of this controversial group of gastropods. Klussmann-Kolb et al. (2008) traced an evolutionary scenario regarding colonisation of different habitats based on phylogenetic hypothesis and they showed that traditional classification of Euthyneura needs to be reconsidered.[2]
2010 taxonomy
Jörger et al. (2010)[6] have redefined major groups within the Heterobranchia and a cladogram showing phylogenic relations of Euthyneura is as follows:[6]
