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 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.

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 47 species worldwide known in 2023,MolluscaBase eds. (2021)MolluscaBase. Acochlidiimorpha.Accessed on 2023-02-13. this group has been the subject of active research since 2010, by which date only 32 species were named. 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 ...

Freshwater Snail
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 gastropod shell, shell, with very few exceptions. Some groups of snails that live in freshwater Respiratory system, respire using gills, whereas Pulmonata, 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 feeding, filter feeders. Freshwater snails are indirectly among the deadliest animals to humans, as they carry parasitic worms that cause schistosomiasis, a disease estimated to kill between 10,000 and 200,000 people annually. There are thousands of known species, and at least 33–38 independent Lineage (evolut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
