Helminthoglypta Walkeriana
The banded dune snail or Morro shoulderband, scientific name ''Helminthoglypta walkeriana'', is a species of air-breathing land snail, a terrestrial animal, terrestrial pulmonate gastropod mollusc in the family Helminthoglyptidae. This species is Endemism, endemic to Morro Bay and the central coast in San Luis Obispo County and Santa Barbara County, in California. Taxonomy At the time the species was divided into two subtaxa (subspecies or varieties): ''H. w. walkeriana'' and *''H. w. morroensis'' The latter was thought to be extinct but was rediscovered. In 2004, it was elevated to species status as ''Helminthoglypta morroensis'' and it inherited the endangered status it had when it was part of ''Helminthoglypta walkeriana''. Both snails together were known as the banded dune snail. Today ''H. walkeriana'' is the Morro shoulderband, and ''H. morroensis'' is the Chorro shoulderband.USFWSMorro Shoulderband and Chorro Shoulderband Five-year Review.September 2006. Conservation T ...

Henry Hemphill
Henry Hemphill (1830–1914) was an American malacologist, a biologist who studies mollusks. In particular he studied land and freshwater mollusca. His collection of land, freshwater, and marine mollusks became holdings of the California Academy of Sciences and Stanford University. He was born in Delaware in 1830. He worked as a bricklayer in San Diego 1865, after making gold prospecting trips in the western states. He collected mollusks as early as 1861. He published catalogues of shells for sale from the 1870s to 1890. He moved to Oakland around 1909. He died in 1914 on July 24 as a result of contact with arsenic. He sold and sent out material labeled with unpublished names, and introduced varieties and formal names. He often used vague terms to describe the locality of specimens. Taxa He named and described many molluscan taxa, including: * ''Fluminicola columbiana'' Hemphill in Henry Augustus Pilsbry, Pilsbry, 1899 - a freshwater snail * ''Helminthoglypta walkeriana'' (H ...

Gastropods Described In 1911
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Molluscs Of The United States
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant taxon, extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater mollusc, freshwater and Terrestrial molluscs, terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 Taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologically advanced of all inve ...

Natural History Of Santa Barbara County, California
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Fauna Of The California Chaparral And Woodlands
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of California
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Luis Obispo County
San Luis Obispo County (), officially the County of San Luis Obispo, is a county on the Central Coast of California. As of the 2020 census, the population was 282,424. The county seat is San Luis Obispo. Junípero Serra founded the Mission San Luis Obispo de Tolosa in 1772, and San Luis Obispo grew around it. The small size of the county's communities, scattered along the beaches, coastal hills, and mountains of the Santa Lucia range, provides a wide variety of coastal and inland hill ecologies to support fishing, agriculture, and tourist activities. California Polytechnic State University has almost 20,000 students. Tourism, especially for the wineries, is popular. Grapes and other agriculture products are an important part of the economy. San Luis Obispo County is the third largest producer of wine in California, surpassed only by Sonoma and Napa counties. Strawberries are the largest agricultural crop in the county. The town of San Simeon is located at the foot of the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
