The gastropods, gasteropods, or univalves, are the largest and most successful class of mollusks, with 60,000-75,000 known living species. This class contains a vast number of marine, freshwater, and terrestrial species. Species include the snails and slugs, abalone, limpets, cowries, conch and most of the other animals that produce seashells.

The first gastropods were exclusively marine, with the earliest representatives of the group appearing in the Late Cambrian (Chippewaella, Strepsodiscus). By the Ordovician period the gastropods were a varied group present in a range of aquatic habitats. Fossil gastropods are less common during the Palaeozoic era than bivalves. By the Carboniferous period many of the shapes we see in living gastropods can be matched in the fossil record, but despite these similarities in appearance the majority of these older forms are not directly related to living forms. It was during the Mesozoic era that the ancestors of many of the living gastropods evolved.

Gastropods are one of the groups that record the changes in fauna caused by the advance and retreat of the Ice Sheets during the Pleistocene epoch.

Conchology is the scientific study of shells of mollusks, a branch of malacology.

Families

(in progress) Create article for each Family

• Ensure all Family articles are taxonomically consistent.
  • Check out families that are not listed in Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005):

• • • Carychiidae (What links to Carychiidae) (Full text search of Carychiidae) --> Carychiinae

There is a family Cloristellidae in Lepetelloidea on ITIS http://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=331102 Where belongs genus Choristella, to Lepetellidae?

• • • add other families there
• Ensure all articles between the Order and Family rank are taxonomically consistent
• Ensure all articles between Family and Genus rank are taxonomically consistent

Species

(in progress)

• Create articles for all Species and for needed Genera. Many species, however, are virtually undescribed. It is better, then, to describe the Genus or, if necessary, just the Family.

• If there is image of the species available then make an article (or start a stub) about the species.

Threatened species

Add information to certain species articles about its local conservation status according local Red Lists.

Species from IUCN

Probably resolved by robots acoording 2007 IUCN Red list.

Canada

Species articles with its status in Canada. Species of gastropods (and all molluscs) assessed by COSEWIC, then they the Canadian Species at Risk Act listed them in the List of Wildlife Species at Risk (not written in the wikipedia list yet). According COSEWIC. 2005. Canadian Species at Risk. Committee on the Status of Endangered Wildlife in Canada. 64 pp.

Norway

(anybody can do it) - make a list and/or make a species article with conservation status in Norway according Kålås, J. A., Viken, Å. og Bakken, T. (red.) 2006. Norsk Rødliste 2006 – 2006 Norwegian Red List. Artsdatabanken, Norway. 330-331. http://www.artsdatabanken.no/Norsk_R%C3%B8dliste_2006_Hele_r5It4.pdf.file

USA

(anybody can do it) - United States Fish and Wildlife Service list of endangered species - find a good source. Make a species articles with conservation status in USA.

other

Proposition of other tasks add here.

Images

Move all free images of gastropods to commons for better categorizing images and for support of other language wikis.

• • Categorize them to family or to species page.

Verify and or determine all gastropod images in commons.

Identification needed:

an unidentified species of Auriculella
