Mid	This article has been rated as Mid-importance on the project's importance scale.
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.

Picture[edit]

I don't know what is it on first picture, but this is not Roman snail (Helix pomatia). I'm sure.

I completely agree. Also, does anyone know about keeping snails as pets? I have had one for over three months now and it is great fun and easy to take care of. They only need to eat left over salad and have some dirt to play around in. Has anyone else shared my experience?

I keep a number of snails also! Join the Petsnails forum if you want to talk to others about it and get more information. --Thegreatloofa 21:24, 24 August 2005 (UTC)[reply]

Article[edit]

I think that much of this article can be merged with the snail page. Some information here is just about snails in general, which could be better placed there. --Thegreatloofa 21:21, 24 August 2005 (UTC)[reply]

I agree. For example, the Description section describess a stylommatophoran in general. Ondrej.korabek (talk) 13:40, 1 April 2023 (UTC)[reply]

Please clarify this sentence[edit]

The following sentence:

  <The snails produce both eggs and sperm in the ovotetis (also called the hermaphrodite gland), but it is later separated into two divisions, a sperm duct and oviduct, respectively.>

doesn't make much sense. Which snails produce both eggs and sperm? Surely only the hermaphrodites do, not all snails, right? What is separated: the ovotetis? (Shouldn't it be "ovotestis", with an "s"?) Is it separated at a later period in the snail's life cycle? At what point in the lifecycle? Or is it separated at a physical place later (as in further along) in the reproductive tract, rather than at a later stage in the snail's development? Someone who knows about this stuff should fix it. Dveej 08:11, 19 June 2006 (UTC)[reply]

Love Darts and Hormone Question[edit]

I remember reading somewhere that the love dart is used to inject a hormone that constricts the vas deferens, thus cutting off bloodflow, but I can't find where I read it in. Does anyone else know about it, or am I having a skittlebrau moment?--Mr Fink (talk) 06:15, 7 May 2008 (UTC)[reply]

Lists of names[edit]

The page contains long lists of nominal taxa that were described in Helix, but otherwise have nothing to do with the topic of the page. For example, the list titled "Many species of Helix have been brought into synonymy:" contains mostly marine or freshwater snails totally unrelated to Helix. Furthermore, there are thousands of such names, so the lists cannot be complete. Linnaeus included in Helix a very broad range of snails, marine, freshwater or terrestrial, and as described a couple paragraphs above, the process of narrowing down the concept of the genus lasted to the early 20th century. These lists were apparenly simply copied from some version of MolluscaBase, and their inclusion here is simply ridiculous. Please, allow them to be removed.

Information relating to Cornu aspersum ("Helix aspersa")[edit]

At several points of the article, the information relates to a species formerly known as H. aspersa. This species is now known to be unrelated to Helix, so any descriptions of its ecology, appearance, distribution, uses, etc. is no longer valid for Helix. These need to be removed to maintain accuracy. Ondrej.korabek (talk) 13:43, 1 April 2023 (UTC)[reply]

Pictures, distribution maps[edit]

Some of the pictures show wrong species: alleged H. philibinensis is H. figulina, H. nucula is H. pronuba, one of the H. lutescens is Cornu aspersum. The distribution maps are obsolete, recent research on the distributions and taxonomic changes has shown these to be very inaccurate. Better remove, they are simply wrong. Ondrej.korabek (talk) 13:47, 1 April 2023 (UTC)[reply]

Species lists contains taxa that are not even related to Helix[edit]

Helix aporina Castro, 1887 belongs to Ponentina (Hygromiidae)

Helix tourannensis Souleyet, 1852 belongs to Acusta (Camaenidae)

Helix hedenborgi L. Pfeiffer, 1846 belongs to Monacha (Hygromiidae)

These need to be removed from a species list of Helix! Ondrej.korabek (talk) 13:54, 1 April 2023 (UTC)[reply]

Done. Thanks for remarking. JoJan (talk) 13: 07, 2 April 2023 (UTC)
