Latiidae
''Latia'' is a genus of very small, air-breathing freshwater snails or limpets, aquatic pulmonate gastropod molluscs in the superfamily Chilinoidea. ''Latia'' is the only genus in the family Latiidae. Species in this genus are the only freshwater bioluminescent molluscs in the world.BERNARD J. BOWDEN (1950)SOME OBSERVATIONS ON A LUMINESCENT FRESHWATER LIMPET FROM NEW ZEALAND. ''Biol Bull'' 99: 373-380. Taxonomy The family Latiidae has been classified within the superfamily Chilinoidea, itself belonging to the clade Hygrophila within the informal group Basommatophora in the informal group Pulmonata (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). There are no subfamilies in the family Latiidae (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). ''Latia'' is the only genus in the family Latiidae, in other words Latiidae is a monotypic family and ''Latia'' is the type genus of the family Latiidae. This genus was previ ...

Latia Neritoides
''Latia neritoides'' is a species of small freshwater snail or limpet, an Aquatic animal, aquatic gastropod mollusc in the family (biology), family Latiidae. The type specimen is in the British Museum. The specific epithet "neritoides" means "like a nerite". The shell of this species has an internal shelf or lamella, but it more closely resembles a shell of a ''Crepidula'' than it does a ''Nerita''. Distribution This species is endemism, endemic to the North Island of New Zealand. Habitat This limpet lives in clean running streams and rivers.Arthur William Baden Powell, Powell A. W. B., ''New Zealand Mollusca'', HarperCollins, William Collins Publishers Ltd, Auckland, New Zealand 1979 Shell description The length of the shell is up to 11 mm. The width of the shell is up to 8 mm. The height of the shell is up to 4.5 mm. If the length of the shell is 8.5 mm, the width of the shell is 6 mm. The height of the shell is 3 mm. The gastropod shell, sh ...

Basommatophora
Basommatophora was a term that was previously used as a taxonomic informal group, a group of snails within the informal group Pulmonata, the air-breathing slugs and snails. According to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), whenever monophyly has not been tested, or where a traditional taxon of gastropods has now been discovered to be paraphyletic or polyphyletic, the term "group" or "informal group" was used. Basommatophora are known from the Carboniferous to the Recent periods.(in Czech) Pek I., Vašíček Z., Roček Z., Hajn. V. & Mikuláš R.: ''Základy zoopaleontologie''. - Olomouc, 1996. 264 pp., . Most of the families in this suborder are air-breathing freshwater snails. The three most abundant families in terms of 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 Siphonariidae on the ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...

Limpet
Limpets are a group of aquatic snails that exhibit a conical shell shape (patelliform) and a strong, muscular foot. Limpets are members of the class Gastropoda, but are polyphyletic, meaning the various groups called "limpets" descended independently from different ancestral gastropods. This general category of conical shell is known as "patelliform" (dish-shaped). All members of the large and ancient marine clade Patellogastropoda are limpets. Within that clade, the members of the Patellidae family in particular are often referred to as "true limpets". Other groups, not in the same family, are also called limpets of one type or another, due to the similarity of their shells' shape. Examples include the Fissurellidae ("keyhole limpet") family, which is part of the Vetigastropoda clade (many other members of the Vetigastropoda do not have the morphology of limpets) and the Siphonariidae ("false limpets"), which use a siphon to pump water over their gills.

Pulmonate
Pulmonata or pulmonates, is an informal group (previously an order, and before that a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous Period to the present. Pulmonates have a single atrium and kidney, and a concentrated, symmetrical, nervous system. The mantle cavity is located on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts.

Hygrophila (Gastropoda)
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 Gastropoda (Po ...

Frederick Hutton (scientist)
Captain Frederick Wollaston Hutton (16 November 1836 – 27 October 1905) was an English-New Zealand scientist who applied the theory of natural selection to explain the origins and nature of the natural history of New Zealand. An army officer in early life, he then had an academic career in geology and biology. He became one of the most able and prolific nineteenth century naturalists of New Zealand. Biography Hutton was born in Gate Burton, Lincolnshire, England, the son of the Rev. Henry Frederick Hutton and his wife Louisa Wollaston, daughter of the Rev. Henry John Wollaston. He passed through Southwell grammar school and the Naval Academy at Gosport, Hampshire. He studied applied science at King's College London before being commissioned in the Royal Welch Fusiliers and fighting in the Crimean War and the Indian Mutiny. Hutton returned to England in 1860, and continued to study geology at Sandhurst, being elected to the Geological Society of London in the same ...

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

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, ...

Type Genus
In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens for ranks up to fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
