Liotiidae is a family of small sea snails, marine gastropod mollusks in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). [2]
The head of the animal is proboscidiform. The epipodial line has a pair of conical lobes and three pairs of cirri.
The white shell has a turbiniform or discoidal shape. It shows longitudinal ribs or is clathrate. The shell shows a fine lamellar sculpture. The circular aperture is feebly nacreous. The thick peristome is continuous and shows a callous varix. The multispiral operculum is hispid, corneous and has a soft, calcareous outer layer (intritacalx) formed of pearly beads that are disposed spirally. [3]
The family Liotiidae belongs to the superfamily Turbinoidea, according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
This family consists of the three following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):
Liotiidae was moved to the redefined superfamily Trochoidea according to Williams et al. (2008). [5]
Genera in this family include:
Cymbuliidae is a family of pelagic sea snails or "sea butterflies", marine gastropod mollusks in the superfamily Cymbulioidea.
The Clionidae are a family of sea angels, which are a group of pelagic marine gastropods.
Turbonillinae is a subfamily of mostly minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.
Pyramidellinae is a taxonomic subfamily of minute sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.
Potamididae, common name potamidids are a family of small to large brackish water snails that live on mud flats, mangroves and similar habitats. They are amphibious gastropod molluscs in the superfamily Cerithioidea.
Neritidae, common name the nerites, is a taxonomic family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum.
The Vermetidae, the worm snails or worm shells, are a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Littorinimorpha. The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails".
Hipponicidae, common name hoof shells or hoof snails, is a family of small sea snails, limpet-like marine gastropod molluscs in the superfamily Vanikoroidea.
Amathinidae, is a taxonomic family mostly consisting of small and minute sea snails, marine heterobranch gastropod molluscs or micromolluscs in the superfamily Pyramidelloidea.
Lottiidae is a family of sea snails, specifically true limpets, marine gastropod mollusks in the superfamily Lottioidea and the clade Patellogastropoda.
Pendromidae is a family of gastropods in the clade Vetigastropoda.
Eotomariidae is an extinct family of gastropods in the clade Vetigastropoda.
Seguenzioidea is a superfamily of minute to medium-sized sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Iravadiidae is a family of minute sea snails, marine gastropod molluscs in the superfamily Truncatelloidea and the clade Littorinimorpha.
Murchisonellidae is a taxonomic family of sea snails, marine opisthobranch gastropod mollusks in the superfamily Murchisonelloidea.
Ptychatractidae is a taxonomic family of sea snails, marine gastropod mollusks in the superfamily Turbinelloidea.
Colloniidae is a family of small sea snails with calcareous opercula, marine gastropod mollusks in the clade Vetigastropoda.
Obtortionidae is a family of sea snails, marine gastropod molluscs in the superfamily Cerithioidea, that is within the clade Cerithimorpha or in clade Sorbeoconcha.
Clathurellidae is a monophyletic family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.
