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.[2] Euthyneura are characterised by several autapomorphies.[2] The Euthyneura are considered to be the most successful and diverse group of Gastropoda.[2] Within this taxon Gastropoda have reached their peak in species richness and ecological diversity.[2] This obvious evolutionary success can probably be attributed to several factors.[2] Marine Opisthobranchia, e.g., have evolved several clades specialised on less utilised food resources such as sponges or cnidarians.[2] 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.[2] Klussmann-Kolb et al. (2008)[2] 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 of Euthyneura is as follows:[6]
