Succinea Eussoensis
''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 ; the width ranges between . 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 whitish with gray or light yellow ...

Succinea Putris
''Succinea putris'' is a species of small air-breathing land snail in the family (biology), family Succineidae, the amber snails. Description The 10-17 (27) x 6-8 mm shell has 3-4 whorls. These are relatively flat and with shallow sutures. The body whorl is massive and the aperture is much greater than 50% of shell height. The spire is small. In color the shell is amber yellow. The visible soft parts are yellow with a reddish hue, which becomes lighter downwards to the sides. The animal can also be dark grey. Distribution The distribution of this species is Palearctic, in the Euro-Siberian region, including the following countries and islands: * Belgium * List of non-marine molluscs of the Czech Republic, Czech Republic * Finland * List of non-marine molluscs of Germany, Germany * List of non-marine molluscs of the Netherlands, Netherlands * List of non-marine molluscs of Poland, Poland * List of non-marine molluscs of Ukraine, UkraineBalashov, I. and N.

Vestigiality
Vestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homology (biology), homologous features in related species. The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of function of a feature that is no longer subject to Directional selection, positive Evolutionary pressure, selection pressures when it loses its value in a changing environment. The feature may be Negative selection (natural selection), selected against more urgently when its function becomes definitively harmful, but if the lack of the feature provides no advantage, and its presence provides no disadvantage, the feature may not be phased out by natural selection and persist across species. Examples of vestigial structures (also called degenerate, atrophied, or rudimentary orga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
