Ampullarior, urspung?

Någon som vet vart ifrån ampullarior har sitt urspung?

The Ampullariidae är uppdelat i flera familjer:

Alsolene, Felipponea, Marisa och Pomace är alla fråån nya världen ( Sydamerika och centralamerika, västindien och södra USA.

Bästa akvariearten enligt mig är från Pomace, närmare bestämt Pomace bridgesii

Afropomus, Lanistes och Saulea ar alla från Afrika dvs gamla världen.

Sist men inte minst Pila som finns både i Asien och Afrika.

The new world genus Asolene (d'Orbigni, 1837) contains 7 species.
The type species is Asolene [COLOR=#0000ff]platae[/COLOR] (described by Matin, 1809 as Helix platea). In the past, this genus was considered as a subspecies of Pomacea (Dall, 1904 and Hylton Scott 1943), but is now recognized as a seperate genus.

The new world genus Felipponea (Dall, 1919) contains 3 known species (however it could turn out to be only 2). The type species is Felipponea neritiformis (Dall, 1919).
These snails live in turbulent waters like small streaming rivers. This is reflected in their neritoid shape (less resitance) and strong, thick shell. Snails with large and fragile shells won't survive the conditions in this environment.

The african genus Lanistes (Montfort, 1810) contains 21 species.
The type species is Lansites carinatus (Olivier, 1804).
A distinguishable feature of the Lanistes genus is the sinistral shell (the shell is turned to the left), while the body is dextral. This paradox is called [COLOR=#0000ff]hyperstrophic sinistral[/COLOR].

The new world genus Marisa (Gray, 1824) contains 2 known species.
Due to their a discoidal shell (the spine isn't elevated above the body whorl and thus making the shell almost flat), these snails are not always recognized as being an apple snails. However, from an based on the anatomy, these snails definately belong to the Ampullariidae snails are are probably closely related to the [COLOR=#810081]Asolene[/COLOR] genus.
In the aquarium trade these snail are often know as the 'giant ramhorn snails'.
Type species is Marisa cornuarietis (Gray, 1824, originally described as Marisa intermedia).
The genus name Ceratodes (Guilding) is a junior synonym for Marisa.

The old world (Africa and Asia) genus Pila contains around 30 species. The type species is Pila [COLOR=#0000ff]ampullacea[/COLOR] (Linné, 1758).
The status of some at least 2 Pila members is still unclear and it remains to be seen wether or not these snails could be classified in a seperate genus: Turbinicola (Annandale & Prashad, 1921) or that it's more justified to create a sub-genus Pila (Turbinicola).
The type species is Turbinicola saxea (Annandale & Prashad, 1929).
Older Pila snails have a calcified inside of the operculum (shell door). This is characteristic for the snails of the Pila genus and hasn't been described by the other genera of the Ampullariidae family.
The eggs are white, calcified and deposited above the water surcae on vegetation, rocks, or other objects. No coloured eggs are known in this genus, which makes the a good exclusion criteria, once the eggs have any colour.

Oj, Pomacea stamträdet blev helt uppfuckad. Skickar den på nytt

Synonyms for Pomacea (Perry 1810) are Ampullarius (Lamarck 1799) and Conchylium (Cuvier 1816).
The New World genus Pomacea inhabits a large geographical area from the southern of the USA to the La Plata Bassin in Argentina.
Taxonomy
Over 100 species are described in the genus Pomacea since 1758. However, the validity of many species is doubtfull and in reality the number of species is much lower. The problem with the taxonomy in Pomacea is thea most species descriptions are based on only a few shells, without a decent detailed anatomical study to descriminate between species. Also the authors often did not take in account the geographical distribution and possible variability within on a single species. A good example of this is the [COLOR=#810081]flagellata[/COLOR] complex: over 30 species have been described, while nowadays, they are all considered to be varieties of a single species, eventually with 4 sub-species.
Many authors attempted to reduce the number valid species and tried to reclassify similar species into single species. At present, about 50 nominal species are known, but even this number is likely higher than the actuall number in the field. The inevitable question here is: "How do you define a species?". In the old-style conchology, it was not uncommon to classify every variation as a new species. This completely neglects species variability and genetic relationships.
Current insights in genetics, evolution and species variability require an new approach in which new techniques are used to address the classification of the Pomacea genus. This implies the use of DNA and chromosome studies, comparing internal morphology, interbreeding experiments, immunological test and a more statistical based analysis of available data.
The newest insights reduce the number of actuall species and subdivides the Pomacea genus in two sub-genera: Pomacea (pomacea) and Pomacea (effusa). Within the two subgenera, several groups are recognized, consisting of species that are very similar and might eventually turn out to be a single species. Below is an overview of the new classification of the Pomacea genus. Keep in mind that this is a hypothesis and is subject to changes. Even further reduction could be possible within the Pomacea (pomacea) canaliculata group (doliodes could well be a synonym for lineata)

Full article on-line available: [[COLOR=#0000ff]Click here[/COLOR]][/LIST]Want to identify an apple snail of the Pomacea genus?
There is no complete identification guide available in the [COLOR=#0000ff]literature[/COLOR].
Keep in mind that many species described, might be different forms of a single species. Many descriptions of species are based solely on only a few, empty shells. Colour, banding and [COLOR=#810081]shell[/COLOR] surface ([COLOR=#0000ff]rough, smooth[/COLOR] etc.) are no good identification points as these might vary a lot within a single species. An example of this variation of shell colour can be seen at the [COLOR=#0000ff]Pomacea canaliculata[/COLOR] pictures. The height of the spine/body whorl isn't a reliable determinant (especially when having only a few snails available) either as this can differ as well within one species.
For the snails of the Pomacea canaliculata group, it's quite hard to distinguish the species as the external differences are subtle and the variation within species is high. A possible way do distinguish these snails is the colour of the eggs*:
SpeciesEgg colourPomacea (pomacea) [COLOR=#0000ff]canaliculata[/COLOR] (Lamarck, 1819)Bright orangePomacea (pomacea) [COLOR=#0000ff]insularum[/COLOR] (D'Orbigny, 1839)PinkPomacea (pomacea) [COLOR=#0000ff]lineata[/COLOR] (Spix, 1827)PinkPomacea (pomacea) doliodes (Reeve, 1856)PinkPomacea (pomacea) [COLOR=#0000ff]haustrum[/COLOR] (Reeve, 1856)GreenPomacea (pomacea) [COLOR=#0000ff]gigas / maculata[/COLOR] (Perry, 1810)Green
* This is based on reported egg colours, and it could well be that even the egg colour varies withing one species. Also the food composition, the development stage of the eggs and the humidity of the air can affect the egg colour.

Synonyms are marked light-grey, doubtfull and uncertain species are marked grey. [LIST]
