Clade of gastropods
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 (small cells) in the procerebrum .[ 1]
Eyes positioned on the tips of the tentacles were considered a synapomorphy of a clade named Geophila (Stylommatophora + Systellommatophora), but a 1972 phylogenomic study found strong support for a clade uniting Ellobioidea (eyes at the base of tentacles) and Systelommatopohra (eyes on the tentacle tips). Stalked eyes thus likely evolved twice independently.[ 1]
