Hygrophila (gastropod)
Hygrophila is a taxonomic superorder of air-breathing freshwater snails, aquatic pulmonate gastropod mollusks within the clade Panpulmonata. MolluscaBase eds. (2020). MolluscaBase. Hygrophila. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=382243 on 2020-12-14 The families in this clade are basically air-breathing freshwater snails including freshwater limpets. The three families with the greatest number of species are the Lymnaeidae (pond snails), the Planorbidae (ramshorn snails) and the Physidae (pouch or bubble snails). These are found in ponds, creeks, ditches, and shallow lakes nearly worldwide. The snails in this clade have their eyes located at the base of their tentacles, rather than at the tips, as in the true land snails Stylommatophora. They have shells that are thin, translucent, and relatively colorless, and they lack an operculum. Taxonomy 1997 taxonomy In the older taxonomy of the Gastrop ...

Lymnaea Stagnalis
''Lymnaea stagnalis'', better known as the great pond snail, is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. The great pond snail is a model organism to study parasitology, neurology, embryonal development and genetic regulation. ''Limnaea stagnalis'' var. ''baltica'' Lindström, 1868: synonym of ''Lymnaea stagnalis'' (Linnaeus, 1758) Distribution The distribution of this species is holarctic, mainly the temperate zones of Northern America, Europe and Asia. The snail can be found in many ponds, lakes and very slow-moving rivers with a rich underwater vegetation. The northernmost populations exist in northern Norway, and in Central Europe, it inhabits even montane ecosystems at 1700 meters above sea level. In the ''Saprobiensystem'' used in Germany to judge the quality of freshwater biotopes, the species has a value of 1.9 and indicates a biotope with a water quality class II, the second-highest.

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Amphiboloidea
Amphiboloidea is a Taxonomy (biology), taxonomic superfamily of air-breathing land snails. Distribution Amphibolids are found in Indo-Pacific intertidal mangrove, saltmarsh and estuarine mudflat habitats. Taxonomy 2005 taxonomy According to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), it is a superfamily in the informal group Basommatophora, within the Pulmonata. This superfamily has contained only one family, the Amphibolidae. 2007 taxonomy Golding et al. (2007)Golding R. E., Ponder W. F. & Byrne M. (2007).

Siphonarioidea
Siphonarioidea is a taxonomic superfamily of air-breathing sea snails or false limpets, marine gastropod mollusks in the clade Panpulmonata. Distribution The Siphonarioidea are broadly distributed across the globe, however they are known to be the most abundant and species diverse in the warmer temperate to subtropical regions. More specifically, they are found within the southern hemisphere of the Indo-Pacific region. They generally inhabit marine benthic regions, specifically the subtidal zones. Description Siphonarioidea are almost entirely marine organisms, as they have been found to have evolved into despite the terrestrial ecosystems inhabited by their ancestors. They inhabit the subtidal zones of marine ecosystems, and resemble true limpets with their non coiled, conical shells. Siphonarioidea are frequently referred to as "false limpets" due to some distinct differences despite their resemblance to these Patellogastropoda. For example, Siphonariid adults' dorso-ventr ...

Ancylidae
Ancylini is a tribe of small, freshwater, air-breathing limpets, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails and their allies. This tribe used to be treated as a family; the current taxonomic placement within Planorbidae is according to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005). Anatomy These animals have a pallial lung, as do all pulmonate snails, but they also have a false gill or "pseudobranch" which can serve perfectly well as a gill in situations where the limpet is unable to reach the surface for air, as is often the case. Genera Genera in the tribe Ancylini include: * ''Ancylus'' Müller, 1773 - type genus * '' Pseudancylus'' * '' Rhodocephala'' * ''Ferrissia'' Walker, 1903 * '' Rhodacmea'' Walker, 1917 * '' Sineancylus'' Gutiérrez Gregoric, 2014 * '' Anisancylus'' Pilsbry & Vanatta, 1924 * '' Burnupia'' Walker, 1912 * '' Gundlachia'' Pfeiffer, 1849 * '' Hebetancylus'' Pilsbry, 1914 * '' Laevapex'' Walker, ...

Physidae
Physidae, common name the bladder snails, is a monophyletic taxonomic family of small air-breathing freshwater snails, aquatic pulmonate gastropod molluscs in the superfamily Lymnaeoidea .MolluscaBase eds. (2021). MolluscaBase. Physidae Fitzinger, 1833. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=160452 on 2021-06-26 Overview These fresh water snails are present in aquariums and ponds, as well as in wild areas. They are commonly referred to as tadpole snails or pouch snails. They eat algae, diatoms and detritus including dead leaves. The populations are regulated by the abundance of food and space. They are widespread, abundant, and tolerant to pollution. These snails are common in the North Temperate to Arctic Zones and throughout the Americas, in readily accessible habitats such as ditches, ponds, lakes, small streams, and rivers. The family has been recognized since the 19th century, and yet there has been no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
