Taxonomy: For all marine species, Project Gastropods uses the taxonomy in the online database WoRMS. When starting a new article, do not use sources of taxonomic information that predate the 2017 revision for all gastropod groups ("Revised Classification, Nomenclator and Typification of Gastropod and Monoplacophoran Families" by Philippe Bouchet & Jean-Pierre Rocroi, Bernhard Hausdorf, Andrzej Kaim, Yasunori Kano, Alexander Nützel, Pavel Parkhaev, Michael Schrödl and Ellen E. Strong in Malacologia, 2017, 61(1–2): 1–526.) (can be dowloaded at Researchgate.net), substituting the previous classification of 2005 Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005). If you need help with any aspect of an article, please leave a note at the Project talk page.
This article was previously labelled as being "A" class, which is considered to be very close to Featured Article in standard. However, it appears to be the case that the proper A-class assessment procedure was not followed when "A" status was first awarded to this article.
The necessary qualifications for "A" class, and a description of the proper process for awarding "A" class, are described here[1].
The article has now been labeled as "B" class. Project Gastropods will attempt to have the article properly assessed to see if it currently qualifies officially for a higher rating, or can rapidly be improved to meet a higher rating standard, but if the article currently cannot qualify as higher than a "B", it will remain as "B" class until it is further improved.
