Acochlidiidae are a taxonomic family of shell-less freshwater gastropods (one of them Palliohedyle weberi lives in brackish water), [1] aquatic gastropod mollusks within the clade Acochlidiacea.
Acochlidiidae was classified as the only family within the superfamily Acochlidioidea Küthe, 1935 in the taxonomy of Bouchet & Rocroi (2005). [4] Palliohedylidae was in turn classified as the only family within the superfamily Palliohedyloidea. [4]
Schrödl & Neusser (2010) [1] redefined the taxonomy of Acochlidiacea in 2010, placing the family Acochlidiidae in the clade Hedylopsacea. [1]
According to Schrödl & Neusser (2010), [1] there are three genera in the family Acochlidiidae: [1]
Acochlidium Strubell, 1892 [1] [5]
Palliohedyle Rankin, 1979 [1]
Strubellia Odhner, 1937 [1]
Neritoidea is a taxonomic superfamily of mostly sea snails, nerites and their allies, marine gastropod mollusks in the order Cycloneritida.
Lower Heterobranchia, also known as the Allogastropoda, is a group of rather specialized, highly evolved sea slugs and sea snails, within the subclass Heterobranchia.
The Cerithioidea is a superfamily of marine, brackish water and freshwater gastropod containing more than 200 genera. The Cerithoidea are included unassigned in the subclass Caenogastropoda. The original name of this superfamily was Cerithiacea, in keeping with common superfamily endings at the time.
Acochlidiacea, common name acochlidians, are a taxonomic clade of very unusual sea snails and sea and freshwater slugs, aquatic gastropod mollusks within the large clade Heterobranchia. Acochlidia is a variant spelling.
The Limacoidei is a taxonomic infraorder of air-breathing land snails, semislugs and slugs, terrestrial pulmonate gastropod molluscs in the suborder Helicina
Umbraculoidea is a superfamily of unusual false limpets with a thin soft patelliform shell, marine gastropod molluscs in the clade Umbraculida, within the clade Euopisthobranchia.
Hedylopsoidea was defined as a taxonomic superfamily of sea slugs, mostly marine gastropod mollusks within the informal group Opisthobranchia according to the taxonomy of Bouchet & Rocroi (2005).
According to the taxonomy of Bouchet & Rocroi (2005), Strubellioidea was a taxonomic superfamily of sea slugs, mostly marine gastropod mollusks within the informal group Opisthobranchia.
Runcinoidea is a taxonomic superfamily or a clade Runcinaecea of sea slugs, marine gastropod mollusks in the order Runcinida
Hedylopsis is a genus of sea slugs, marine gastropod mollusks within the clade Acochlidiacea.
Asperspina is a genus of sea slugs, marine gastropod mollusks within the clade Acochlidiacea.
Parhedylidae are a taxonomic family of sea slugs, marine gastropod mollusks in the superfamily Parhedyloidea.
Tantulum elegans is a species of freshwater slug, an aquatic shell-less gastropod mollusk within the clade Acochlidiacea.
Strubellia paradoxa is a species of freshwater slug, a shell-less freshwater gastropod, an aquatic gastropod mollusk within the clade Acochlidiacea.
Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivores and some are filter feeders.
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.
Acochlidium fijiiensis is a species of freshwater gastropod, an aquatic gastropod mollusc within the family Acochlidiidae. Acochlidium fijiiensis has no shell.
Acochlidium is a genus of freshwater slugs, an aquatic gastropod molluscs in the family Acochlidiidae.
Pseudunela is a genus of minute sea slugs, acochlidians, shell-less marine or temporary brackish or brackish gastropod mollusks in the clade Acochlidiacea.
Panpulmonata is a taxonomic clade of snails and slugs in the clade Heterobranchia within the clade Euthyneura.
