Biomphalaria Pfeifferi
''Biomphalaria pfeifferi'' is a species of air-breathing freshwater snail, an aquatic animal pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails. This snail is a medically important pest, because of transferring the disease schistosomiasis. Distribution ''Biomphalaria pfeifferi'' is an African species.

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about ance ...

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 ...
