Velutinidae is a family of small sea snails, marine gastropod molluscs in the clade Littorinimorpha. [1] [2] [3]
The shell of these animals is very thin and delicate, and internal, completely covered by the mantle (which has fused lobes) so the appearance of these animals more closely resembles that of sea slugs rather than sea snails.
The following two subfamilies were recognized in the taxonomy of Bouchet & Rocroi (2005): [1]
Genera within the family Velutinidae include:
Subfamily Lamellariinae A. D. d'Orbigny, 1841
Subfamily Velutininae Gray, 1840
Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails, but also including some freshwater snails and land snails.
Olive snails, also known as olive shells and olives, scientific name Olividae, are a taxonomic family of medium to large predatory sea snails with smooth, shiny, elongated oval-shaped shells.
Lamellariinae is a subfamily of small slug-like sea snails, marine gastropod molluscs belonging to the family Velutinidae, in the clade Littorinimorpha.
Lamellaria is a genus of small slug-like sea snails, marine gastropod molluscs in the family Velutinidae.
Helcionelloida is an extinct group of ancient molluscs. These are the oldest known conchiferan molluscs, that is, they had a mineralised shell. Some members of this class were mistaken for Monoplacophorans. The class was erected by Peel in 1991.
Liotiidae is a family of small sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Eucyclidae is a family of gastropods in the superfamily Seguenzioidea.
Phenacolepadidae is a family of small sea snails or false limpets, marine gastropod mollusks in the clade Cycloneritimorpha.
Cylichnidae, common name the "chalice bubble snails" or "canoe bubble snails" is a family of sea snails or bubble snails, marine gastropod mollusks in the superfamily Cylichnoidea.
Coreospiridae is an extinct family of Paleozoic molluscs of uncertain position taxonomically. They might be snails (Gastropoda), Helcionelloida, or they might be Monoplacophora.
The Cerithioidea is a superfamily of marine, brackish water and freshwater gastropod containing more than 200 genera. The Cerithoidea are included in the clade Sorbeoconcha. The original name of this superfamily was Cerithiacea, in keeping with common superfamily endings at the time.
The Testacelloidea are a superfamily of air-breathing land snails and slugs, terrestrial gastropod mollusks in the suborder Helicina of the order Stylommatophora.
Olivoidea is a taxonomic superfamily of minute to medium-large predatory sea snails, marine gastropod mollusks in the clade Neogastropoda.
Trenella is the sole genus in the Trenellidae, an extinct family of paleozoic Yochelcionellids.
Curnonidae is a small family of sea slugs, nudibranchs, shell-less marine gastropod molluscs, in the clade Euthyneura. There are no subfamilies in Charcotiidae.
The Cornirostridae is a taxonomic family of sea snails, marine gastropod mollusks in the informal group Lower Heterobranchia.
Colubrariidae are a taxonomic family of medium-sized sea snails, marine gastropod mollusks in the superfamily Buccinoidea. This family has no subfamilies.
Yochelcionelloidea is an extinct superfamily of paleozoic molluscs of uncertain position. The earliest yochelcionellids are known from the Middle Tommotian, but they are most diverse from the Botomian through the early Middle Cambrian.
Marsenina is a genus of small slug-like sea snails, marine gastropod molluscs in the subfamily Lamellariinae within the family Velutinidae.
