Triphoridae are a family of very small sea snails, marine gastropod molluscs in the informal group Ptenoglossa in the clade Hypsogastropoda. Almost all the species in this family are micromollusks.

hell description

The shells of triphorids are small and extremely high-spired, with numerous narrow whorls which often have distinctive sculpture. The majority of species in this family are left-handed or sinistral. (For an explanation of this term, see the section on chirality in the article gastropod shell.)
