Abyssochrysoidea is a superfamily of deep-water sea snails, marine gastropod mollusks unassigned in the order Caenogastropoda. [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.
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".
Pendromidae is a family of gastropods in the clade Vetigastropoda.
Seguenziidae is a family of very small deepwater sea snails, marine gastropod mollusks in the superfamily Seguenzioidea.
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.
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.
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.
Litiopidae, common name litiopids, is a family of small sea snails, marine gastropod molluscs in the clade Sorbeoconcha.
Ifremeria nautilei is a species of large, deepwater hydrothermal vent sea snail, a marine gastropod mollusk in the family Provannidae, and the only species in the genus Ifremeria. This species lives in the South Pacific Ocean
Urocoptoidea is a superfamily of land snails, gastropods in the suborder Helicina.
Trenchia is a genus of sea snails, marine gastropod mollusks, unassigned in the superfamily Seguenzioidea.
Turbinelloidea is a superfamily of sea snails in the order Neogastropoda. It comprises the following families:
Choristellidae is a family of gastropods in the superfamily Seguenzioidea (according to the taxonomy of the Gastropoda
Cocculinida is an order of deepwater limpets, in the subclass Neomphaliones.
