Succinea Africana
''Succinea'', common name the amber snails, is a large genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Succineidae. MolluscaBase eds. (2021). MolluscaBase. Succinea Draparnaud, 1801. Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=181586 on 2021-02-23 The common name refers to the fact that live snails in this genus are translucent and similar to amber in appearance. Description The length of the shell ranges between 9.4 mm and 17 mm, the width between 6.8 mm and 11.5 mm. The dextrous, pointed ovoid shell consists of 3⅓ - 3½ whorls. It is thin-walled, glossy and translucent. The protoconch is very compact. The spire is short and consists mainly of a large, wide body whorl and an oval aperture with a sharp angle at the top. The deep sutures are prominent.The interior surface of the aperture is cream-colored or white. The shell is usually light brown, but may be whiti ...

Arch
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Succineidae
Succineidae are a family of small to medium-sized, air-breathing land snails (and slugs), terrestrial pulmonate gastropod molluscs in the superfamily Succineoidea.MolluscaBase eds. (2021). MolluscaBase. Succineidae Beck, 1837. Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=181585 on 2021-02-23 They are commonly called amber snails because their thin fragile shells are translucent and amber-colored. They usually live in damp habitats such as marshes. Succineidae is the only family in the superfamily Succineoidea. The soft parts of the animal appear to be too large for the shell.Janus, Horst, 1965. ‘’The young specialist looks at land and freshwater molluscs’’, Burke, London Anatomy In this family, the number of haploid chromosomes varies greatly. The most common totals are less than 10, and also lies between 21 and 25, but other values are also possible (according to the values in this table).Barker G. M ...

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. In Egypt it has been detected in water bodies of the Nile Delta. * Western Africa: Benin, Burkina Faso, Côte d'Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Niger, Nigeria and Senegal, Sarr A., Kinzelbach R. & Diouf M.

Physella Acuta
''Physella acuta'' is a species of small, left-handed or sinistral, air-breathing freshwater snail, an aquatic gastropod mollusk in the family Physidae. Common names include European physa, tadpole snail, bladder snail, and acute bladder snail. In addition, ''Physa acuta'', ''Physa heterostropha'' (Say, 1817) and ''Physa integra'' (Haldeman, 1841) are synonyms of ''Physella acuta'' (Draparnaud, 1805). Etymology The etymology of the name ''Physella'' is obscure but could be ultimately from a Greek root. "Physella" (as a place name) is recorded in Giovanni Gemisto's printed edition of Pliny's encyclopedia, perhaps lifted from Ermolao Barbaro's ''Castigationes Plinianae'' where it is recorded as ''Physcella''. The French naturalist Jacques Draparnaud was the first to describe a species of the genus ''Physella'' and coined the name. Shell description Snails in the family Physidae have shells that are sinistral, which means that if the shell is held with the aperture facing the ob ...
