rotundicauda

Rotundicauda is a Latin-derived species epithet used in the scientific names of several organisms. It is not a taxon by itself but appears in binomial names across different genera. The epithet derives from rotundus (rounded) and cauda (tail), and it typically refers to a rounded tail or posterior body feature observed by the describer.

Taxonomic usage: Because rotundicauda is a descriptive epithet rather than a genus, multiple species across diverse lineages may share it. It is found among crustaceans, particularly crabs and shrimps, and it may also appear in other invertebrate groups. Each rotundicauda species belongs to a different genus and is not necessarily closely related to other rotundicauda species.

Nomenclatural notes: When a species is transferred to another genus, the epithet often remains the same if it is not already used in the target genus; otherwise a replacement name may be needed.

References: For precise information on a specific rotundicauda species, consult taxonomic databases such as the World Register of Marine Species or Integrated Taxonomic Information System, as well as the original descriptions in the taxonomic literature.
