Neritidae: Genera, Taxonomy & Distribution
Neritidae, common name the nerites, is a family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum. The family Neritidae includes marine genera such as Nerita, marine and freshwater genera such as Neritina, and freshwater and brackish water genera such as Theodoxus.

How Neritidae connects Entity context
Entity context groups extracted connections by relationship type. Counts show recurrence in the analyzed source; the examples are research signals, not claims about importance.
The extracted context around Neritidae shows recurring relationship patterns in the source. For example, Neritidae → Biostratigraphy, California, Catillus, Classification, Contributions, Gray, Humphrey, Kern River Area, Lamarck, London, Malacologia, Miocene Gastropods, Navicella, Neritacea, Notes, Proceedings, Professional Paper, Rocroi, The Neritidae, This Another extracted example is Neritidae → Baker, Bouchet, Catilinae Gray, Gastropoda, Kittl, Neritariinae Wenz, Neritellinae Gray, Neritinae Rafinesque, Neritinini Poey, Orthopomatini Gray, Poey, Proto, Rocroi, Septariini Jousseaume, Stenopomatini Gray, Theodoxini Bandel, This, Velatinae Bandel. Use these groups to spot repeated connection types before inspecting the individual relationships.

Related concept clusters Concept neighborhoods
Concept neighborhoods group terms that sit near one another in the extracted graph. They are useful for discovering adjacent language and context, but proximity does not by itself imply a factual relationship.
The concept neighborhoods around Neritidae bring nearby vocabulary together. In this analysis, examples include Synonyms, Genus and Bathynerita. Use the clusters to find adjacent concepts and terminology that may deserve separate research.

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Neritidae, one of the stronger structural bridges in this analysis connects Neritidae with Genera. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.

Source & methodology
TTTA analyzes the structure around Neritidae to surface related topics, entities, relationships, concept neighborhoods and bridge connections. Use the map to explore areas such as Genera, Taxonomy & Distribution, including less central topics that may reveal useful research gaps. Automatically extracted connections are research leads rather than rewritten encyclopedia content.
