Triphoridae is a family of very small sea snails, marine gastropod molluscs in the informal group Ptenoglossa, within the clade Hypsogastropoda.

[1] Species of this family can be found worldwide, but the major part occurs in the Indo-Pacific Region.

Most species live between the intertidal zone and offshore to a depth between 200 m to 500 mm (exceptionally below 1,000 m).

Facts about their taxonomy are rather scant, complicated by the high diversity and the intra- and inter-specific variability of the species.

[2] The following subfamilies were recognized in the taxonomy of Bouchet & Rocroi of 2005: Gründel (1975), stated that the correct family name is Triforidae Jousseaume, 1884 and not Triphoridae, but this is only true when the genera Triforis and Triphora are placed in the same family (Kosuge, 1976).
