Etymology of Taxon Names
The information below provides a list containing descriptions of the origins of ICTV taxon names starting at the rank of realm and going down to the rank of family. This information is derived from the proposals that were submitted when each taxon was created. Links to these proposals, links to ICTV report chapters, and links to publications (through PMIDs) are provided when available.
We thank Stuart Siddell for compiling this list of name origins. Etymological information for taxa below the rank of family, can be found in the relevant ICTV Online (10th) Report chapters. If you have any comments or corrections, please contact us by sending an email to [email protected].
