Abyssochrysoidea is a superfamily of deep-water sea snails, marine gastropod mollusks unassigned in the orderCaenogastropoda. [1]
These marine snails are part of the fauna of the hydrothermal vents and other deep-water habitats.
Families within the superfamily Abyssochryoidea include:
These two families Provaniidae and Abyssochrysidae were previously placed in the "Zygopleuroid group" (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Subsequently Provannidae was placed in the superfamily Abyssochrysoidea by Kaim et al. (2008) [2] and then Abyssochrysidae was also moved to Abyssochrysoidea. [3]
Neritoidea is a taxonomic superfamily of mostly sea snails, nerites and their allies, marine gastropod mollusks in the order Cycloneritida.
Neomphaloidea is a superfamily of deep-sea snails or limpets, marine gastropod mollusks. Neomphaloidea is the only superfamily in the order Neomphalida.
Columbariidae, known as pagoda shells, are a family of large deepwater sea snails, marine gastropod mollusks in the superfamily Turbinelloidea. Some 60 extant species have been described.
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".
Lissotesta is a genus of minute sea snails or micromolluscs, marine gastropod molluscs, unassigned in the superfamily Seguenzioidea.
Pendromidae is a family of gastropods in the clade Vetigastropoda.
Liotiidae is a family of small sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Abyssochrysidae is a family of sea snails, marine gastropod mollusks in the clade Caenogastropoda.
Provannidae is a family of deep water sea snails, marine gastropod mollusks in the superfmaily Abyssochrysoidea.
Scolodontidae is a taxonomic family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Scolodontoidea
Bathysciadiidae is a family of sea snails, deep-sea limpets, marine gastropod mollusks in the clade Cocculiniformia.
Hokkaidoconchidae, common name hokkaidoconchids, is an extinct family of deep-water sea snails, marine gastropod mollusks.
Seguenzioidea is a superfamily of minute to medium-sized sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Olivoidea is a taxonomic superfamily of minute to medium-large predatory sea snails, marine gastropod mollusks in the clade Neogastropoda.
Murchisonellidae is a taxonomic family of sea snails, marine opisthobranch gastropod mollusks in the superfamily Murchisonelloidea.
The Hyalogyrinidae is a taxonomic family of sea snails, marine gastropod mollusks in the informal group Lower Heterobranchia.
This overview lists proposed changes in the taxonomy of gastropods at the family level and above since 2005, when the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) was published. In other words, these are recent updates in the way various groups of snails and slugs are classified.
Ebala is a genus of sea snails, marine gastropod mollusks in the subfamily Ebalinae, family Murchisonellidae.
Urocoptoidea is a superfamily of land snails, gastropods in the suborder Helicina.
Turbinelloidea is a superfamily of sea snails in the order Neogastropoda. It comprises the following families:
