Umbraculidae are a taxonomic family of unusual sea snails or limpets, marine opisthobranch gastropod molluscs in the clade Umbraculida. [1]
This family has a global distribution in tropical and subtropical seas.
Genera within the family Umbraculidae include:
Rapaninae is a subfamily of predatory sea snails, marine gastropod mollusks in the family Muricidae.
Amphibolidae is a family of air-breathing snails with opercula, terrestrial pulmonate gastropod molluscs.
The Cassidae are a taxonomic family of medium-sized, large, and sometimes very large sea snails commonly called helmet snails or bonnet snails. These are marine gastropod mollusks in the superfamily Tonnoidea and the clade Littorinimorpha.
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.
Volva is a genus of sea snails, specifically cowry allies or ovulids, marine gastropod molluscs in the family Ovulidae.
The Melongenidae, the crown conchs and their relatives, are a taxonomic family of large to very large marine gastropods in the superfamily Buccinoidea.
Pterotracheidae is a family of medium-sized to large floating sea snails, pelagic gastropod molluscs. They are in the superfamily Pterotracheoidea along with two other similar pelagic families, the Atlantidae and the Carinariidae.
The Calyptraeidae are a family of small to medium-sized marine prosobranch gastropods.
Mitridae, known as mitre shells, are a taxonomic family of sea snails, widely distributed marine gastropod molluscs in the clade Mitroidea.
Umbraculum, common name the "umbrella slugs" is a genus of unusual sea snails or false limpets, marine gastropod molluscs in the family Umbraculidae.
The Bursidae, common name "frog snails" or "frog shells", are a rather small taxonomic family of large sea snails, marine gastropod predatory snails in the clade Littorinimorpha.
Hipponicidae, common name hoof shells or hoof snails, is a family of small sea snails, limpet-like marine gastropod molluscs in the superfamily Vanikoroidea.
Hipponix, common name hoof snails or hoof shells, is a genus of small sea snails with limpet-like shells, marine gastropod molluscs in the family Hipponicidae, the hoof snails. Many of the species in this genus have white shells.
Persiculinae is a taxonomic subfamily of minute to small predatory sea snails, marine gastropod mollusks. This subfamily includes several species which are micromollusks.
Costellariidae sometimes called the "ribbed miters" is a taxonomic family of minute to medium-sized predatory sea snails, marine gastropod mollusks. This family of snails is also sometimes referred to as Vexillum miters. The main family of miter shells however is Mitridae, a closely related group.
Colubrariidae are a taxonomic family of medium-sized sea snails, marine gastropod mollusks in the superfamily Buccinoidea. This family has no subfamilies.
Clavatulidae is a taxonomic family of sea snails, marine gastropod mollusks in the superfamily Conoidea. The family is not well differentiated morphologically.
Voluta is a genus of medium to large sea snails, marine gastropod molluscs in the family Volutidae, the volutes.
Ergalataxinae is a taxonomic subfamily of small to medium-sized predatory sea snails, marine gastropod mollusks within the family Muricidae, the rock snails. In this subfamily, the aragonitic shell has 0–2 varices.
Tegulidae is a family of small to large sea snails, marine gastropod mollusks in the superfamily Trochoidea.
