Mexipyrgus is a genus of very small freshwater snails, aquatic gastropod mollusks in the family Cochliopidae. [1]
A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Freshwater snails are gastropod mollusks which live in freshwater. 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. Most feed on algae, but many are detritivors and some are filter feeders.
An aquatic animal is an animal, either vertebrate or invertebrate, which lives in the water for most or all of its lifetime. Many insects such as mosquitoes, mayflies, dragonflies and caddisflies have aquatic larvae, with winged adults. Aquatic animals may breathe air or extract oxygen that dissolved in water through specialised organs called gills, or directly through the skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land). This designation is paraphyletic.
Species within the genus Mexipyrgus include:
Dwight Willard Taylor (1932–2006) was an American malacologist and paleontologist, a researcher on mollusks. His undergraduate work was at the University of California, Berkeley and his PhD was from Harvard University.
Conidae, with the current common name of "cone snails," is a taxonomic family of predatory sea snails, marine gastropod molluscs in the superfamily Conoidea.
Sterculia is a genus of flowering plants in the mallow family, Malvaceae: subfamily Sterculioideae. Members of the genus are colloquially known as tropical chestnuts. The scientific name is taken from Sterculius of Roman mythology, who was the god of manure; this is in reference to the unpleasant aroma of the flowers of this genus. Sterculia may be monoecious or dioecious, and flowers unisexual or bisexual.
Conoidea is a superfamily of predatory sea snails, marine gastropod mollusks within the suborder Hypsogastropoda. This superfamily is a very large group of marine mollusks, estimated at about 340 recent valid genera and subgenera, and considered by one authority to contain 4,000 named living species.
In scientific nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name, although the term is used somewhat differently in the zoological code of nomenclature. For example, Linnaeus was the first to give a scientific name to the Norway spruce, which he called Pinus abies. This name is no longer in use: it is now a synonym of the current scientific name, Picea abies.
Alestes is a genus in the family Alestidae, known as the "African Characidae" as they are found exclusively on that continent. As suggested by that name, they Alestidae was formerly included in Characidae. Myletes is a synonym of Alestes, but the former name has historically also been used for various South American serrasalmines.
Ringiculidae are a family of minute deep water sea snails, marine gastropod mollusks or micromollusks in the informal group Lower Heterobranchia.
The Littorinidae are a taxonomic family of over 200 species of sea snails, marine gastropod molluscs in the clade Littorinimorpha, commonly known as periwinkles and found worldwide.
Comitas is a genus of medium-sized sea snails, marine gastropod molluscs in the family Pseudomelatomidae.
Mexipyrgus carranzae is a species of very small freshwater snail, an aquatic gastropod mollusk in the family Cochliopidae.
Cochliopidae is a family of small freshwater snails with gills and an operculum, aquatic gastropod mollusks. Paludestrina d'Orbigny, 1840 is an archaic synonym, and has been placed on the Official Index of Rejected and Invalid Names by ICZN Opinion 2202.
Flabellina is a genus of sea slugs, specifically aeolid nudibranchs. These animals are marine gastropod molluscs in the family Flabellinidae.
Pseudoplectania is a genus of fungi in the family Sarcosomataceae. The genus contains 12 species. Pseudoplectania ryvardenii was described in 2012, while Pseudoplectania carranzae was transferred to the genus in 2013.
Trochita is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae, the slipper snails or slipper limpets, cup-and-saucer snails, and Chinese hat snails.
Otitoma is a genus of sea snails, marine gastropod mollusks in the family Pseudomelatomidae.
Trinchesia is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Trinchesiidae. All species were transferred to Tenellia as a result of a DNA phylogeny study in 2016. The genus was dismembered and broken into several smaller genera in 2017 with further DNA evidence and a re-interpretation of genus and family characteristics.
Truncatelloidea is a superfamily of snails, gastropod mollusks in the clade Caenogastropoda.
Nebularia is a genus of predatory sea snails, marine gastropod mollusks within the family of Mitridae. This name was originally proposed as a subgenus of the genus Mitra. The type species of this genus is Nebularia contractaSwainson, 1820.
Cochliolepis is a genus of small sea snails, marine gastropod mollusks in the family Tornidae.
Turridae is a taxonomic family name for a number of predatory sea snails, marine gastropod mollusks in the superfamily Conoidea.
