Acochlidiidae
Acochlidiidae are a taxonomic family of shell-less freshwater gastropods (one of them ''Palliohedyle weberi'' lives in brackish water),Schrödl M. & Neusser T. P. (2010). "Towards a phylogeny and evolution of Acochlidia (Mollusca: Gastropoda: Opisthobranchia)". ''Zoological Journal of the Linnean Society'' 158: 124-154. . aquatic gastropod mollusks within the clade Acochlidiacea. 2005 taxonomy Acochlidiidae was classified as the only family within the superfamily Acochlidioidea Küthe, 1935 in the taxonomy of Bouchet & Rocroi (2005). Palliohedylidae was in turn classified as the only family within the superfamily Palliohedyloidea. 2010 taxonomy Schrödl & Neusser (2010) redefined the taxonomy of Acochlidiacea in 2010, placing the family Acochlidiidae in the clade Hedylopsacea. Genera According to Schrödl & Neusser (2010), there are three genera in the family Acochlidiidae: '' Acochlidium'' Strubell, 1892 * ''Acochlidium amboinense'' Strubell, 1892Rudman W. B. (17 June ...

Hedylopsacea
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. Description These are mostly very small animals, without a shell or gills, distinguished by the visceral mass being sharply set off from the rest of the body. Being a small group with only 30 species worldwide known in 2010, and 32 species described in 2011, and 33 in 2012 (+9 undescribed ''Pontohedyle'' species), these slugs are morphologically and biologically highly aberrant and diverse, comprising a series of unusual characters (e.g. secondary gonochorism, lack of copulatory organs, asymmetric radulae). Most acochlidians live interstitially in marine sands, while some have conquered limnic systems (uniquely within opisthobranch gastropods). Taxonomy Nils Hjalmar Odhner established this taxon as a family in 1937, when he created the families Microhedylid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Freshwater Snail
Freshwater snails are gastropod mollusks which 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 (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...
