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.

Scientific classification
Kingdom:	Animalia
Phylum:	Mollusca
Class:	Gastropoda
Subcohort:	Panpulmonata
Superorder:	Eupulmonata Haszprunar & Huber, 1990
Orders
Systellommatophora Stylommatophora Ellobiida

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]
