List Of Non-marine Molluscs Of Madagascar
The non-marine molluscs of Madagascar are a part of the molluscan fauna of Madagascar (wildlife of Madagascar). In tropical rainforests of Madagascar, there is high diversity of species of terrestrial gastropods and many species has low population density, so many of them are "extremely rare". About 50% of land snails in Madagascar are related to land snails in Africa. Freshwater gastropods Pachychilidae the genus '' Madagasikara'' is endemic to Madagascar, 5 species * ''Madagasikara spinosa'' (Lamarck, 1822) – the previously used name ''Melanatria fluminea'' being not valid, endemic * ''Madagasikara madagascariensis'' (Grateloup, 1840) – endemic * ''Madagasikara johnsoni'' (E.

Planorbidae
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals. Being air breathers like other ''Panpulmonata'', planorbids do not have gills, but instead have a lung. The foot and head of planorbids are rather small, while their thread-like tentacles are relatively long. Many of the species in this family have coiled shells that are planispiral, in other words, the shells are more or less coiled flat, rather than having an elevated spire as is the case in most gastropod shells. Although they carry their shell in a way that makes it appear to be dextral, the shell of coiled pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyclophoridae
Cyclophoridae is a taxonomic family of small to large tropical land snails with an operculum, terrestrial gastropod mollusks in the order Architaenioglossa belonging to the subclass Caenogastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). This diverse family with many species is now limited to the representatives in the tropics and subtropics of the Old and New World. Their fossil history dates back through the Early Tertiary to the Cenomanian age of the Cretaceous. Description The dextral shells are mostly of small and rarely medium size. The form of the shell varies from discoidal to turbinate. The round aperture is often modified, sometimes with an incision or a constriction. The last whorl can sometimes be disconnected and then extends strongly from the winding plane. The operculum is generally circular, which can be retracted deeply into the shell. Its form is multispiral and can be calcified or lacking calcareous overlay. The outer la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Invertebrates
''African Invertebrates'' is a peer-reviewed open access scientific journal that covers the taxonomy, systematics, biogeography, ecology, conservation, and palaeontology of Afrotropical invertebrates, whether terrestrial, freshwater, or marine. It is published by Pensoft Publishers on behalf of the KwaZulu-Natal Museum and the editor-in-chief is David G. Herbert (KwaZulu-Natal Museum). History The journal was established in 1906 as the ''Annals of the Natal Government Museum'' and after 1910 renamed to ''Annals of the Natal Museum''. In 1989, the journal stopped publishing archaeological and anthropological papers, which was split of to a new journal, the ''Natal Museum Journal of Humanities'' (later: ''Southern African Humanities''), while the ''Annals of the Natal Museum'' were restricted to the natural sciences. The journal obtained its name in 2001 when its scope was limited to the study of invertebrates. Abstracting and indexing The journal is abstracted and indexed in: ...

Radix Natalensis
''Radix natalensis'' is a species of freshwater snail, an aquatic gastropod mollusc in the family Lymnaeidae. This species occurs widely in Africa. It is a major intermediate host for ''Fasciola gigantica'' in Africa. Placement of this species in the genus ''Radix'' was confirmed by Correa et al. (2010). Distribution ''Radix natalensis'' is a widespread species in Africa, occurring from northern Africa to southern Africa: * Northern Africa: Algeria, Tunisia, Egypt, Sudan. There are also findings of distribution of ''Radix natalensis'' in Algeria 8–10,000 years ago.
