What is "stylommatophora"

Stylommatophora \Sty*lom`ma*toph"o*ra\, n. pl. [NL., fr. Gr. ? column + ? eye + fe`rein to bear.] (Zo["o]l.) A division of Pulmonata in which the eyes are situated at the tips of the tentacles. It includes the common land snails and slugs. See Illust. under Snail.

Stylommatophora is a taxon of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This taxon is considered to be a clade. It used to be regarded as an infraorder (also sometimes was considered to be an order). This taxon includes the majority of land snails and slugs.

The two strong synapomorphies of Stylommatophora are a long pedal gland placed beneath a membrane and two pairs of retractile tentacles (Dayrat & Tillier).

Several families in this group contain species of snails and slugs that create love darts.

Stylommatophora are known from the Cretaceous to the Recent periods.
