Biomphalaria Havanensis
''Biomphalaria havanensis'', common name the ghost rams-horn, is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails. The shell of this species, like all planorbids is sinistral in coiling, but is carried upside down and thus appears to be dextral. Distribution ''Biomphalaria havanensis'' is a Neotropical species. Distribution of ''Biomphalaria havanensis'' include: * CubaVázquez A. A. & Perera S. (2010). "Endemic Freshwater molluscs of Cuba and their conservation status". ''Tropical Conservation Science'' 3(2): 190-199HTMPDF

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Biomphalaria Tenagophila
''Biomphalaria tenagophila'' is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails. This species is medically important pest, because of transferring the disease intestinal schistosomiasis. (Intestinal schistosomiasis is the most widespread of all types of schistosomiasis). The parasite ''Schistosoma mansoni'', which ''Biomphalaria'' snails carry, infects about 83.31 million people worldwide. The shell of this species, like all planorbids is sinistral in coiling, but is carried upside down and thus appears to be dextral. Taxonomy ''Biomphalaria tenagophila'' was originally discovered and described under the name ''Planorbis tenagophilus'' by the French naturalist Alcide d'Orbigny in 1835. d’Orbigny A. (1835) Synopsis terrestrium et fluviatilium molluscoum, in suo per Americam meridionalem itinere collectorum. ''Magasin de zoologie'' 5(62): 1–44Page 26 Orbigny (1835) referred its distrib ...

Biomphalaria Glabrata
''Biomphalaria glabrata'' is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails. ''Biomphalaria glabrata'' is an intermediate snail host for the trematode ''Schistosoma mansoni'', which is one of the main schistosomes that infect humans. This snail is a medically important pest, because of transferring the disease intestinal schistosomiasis, the most widespread of all types of schistosomiasis. The parasite ''Schistosoma mansoni'' (which these snails and other ''Biomphalaria'' snails carry) infects about 83.31 million people worldwide. ''Biomphalaria glabrata''/''Schistosoma mansoni'' provides a useful model system for investigating the intimate interactions between host and parasite. There is a great deal of information available about this snail, because it has been, and continues to be, under intensive study by many malacologists, parasitologists and other researchers, on account of its medi ...
