Eupulmonata
Eupulmonata is a taxonomic clade of air-breathing gastropod molluscs. The great majority of this group are land snails and slugs, but some are intertidal or inhabit coastal saltmarshes and mangroves.
Possible synapomorphy of the group are globineurons in the procerebrum.
Eyes positioned on the tips of the tentacles were considered a synapomorphy of a clade named Geophila, but a 1972 phylogenomic study found strong support for a clade uniting Ellobioidea and Systelommatopohra. Stalked eyes thus likely evolved twice independently.
