Helicarion Mastersi
''Helicarion mastersi'' is a species of air-breathing land snail, also referred to as a semi-slug because of its small shell. It is a terrestrial pulmonate gastropod mollusc in the family Helicarionidae. The specific name ''mastersi'' is in honor of the Australian malacologist George Masters (1837-1912), who collected the type specimen. Subspecies Subspecies include: * ''Helicarion mastersi callidus'' Iredale, 1941 * ''Helicarion mastersi mastersi'' (Cox, 1868) Distribution This species is found in New South Wales, Australia. The type locality is Kiama, New South Wales, Australia. Description ''Helicarion mastersi'' was originally described (under the name ''Vitrina mastersi'') by James Charles Cox in 1868. Cox's original text (the type description) reads as follows: Ecology This semislug lives in closed Eucalyptus forests. It is primarily an arboreal species, but it can also be found in leaf litter Plant litter (also leaf litter, tree litter, soil litter ...

Pigeon House Mountain
Pigeon House Mountain (Indigenous languages of Australia, Aboriginal: ''Didthul'') is a mountain at an elevation of on the Budawang Range that is situated within the Morton National Park, located on the South Coast (New South Wales), South Coast region of New South Wales, Australia. The prominent remnant of a two tier sandstone structure, the nearest town is Milton, New South Wales, Milton. Pigeon House Mountain is a popular walking destination, taking an average of three to four hours for a complete ascent and descent from the car park. Pigeon House Mountain is home to eastern grey kangaroos and superb lyrebirds. Etymology The mountain was first seen by Captain James Cook at 7 a.m. on 21 April 1770, during his voyage of discovery along Australia's eastern coast. Cook described - The Aboriginal name for the mountain is ''Didthul'', ''Didhol'', or ''Dithol'' which means "woman's breast" on account of the distinctive shape of the mountain.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiama, New South Wales
Kiama () is a coastal town 120 kilometres south of Sydney in the Illawarra. One of the main tourist attractions is the Kiama Blowhole. Kiama features several popular surfing beaches and caravan parks, and numerous alfresco cafes and restaurants. Its proximity to the south of Sydney makes it an attractive destination for many day-trippers and weekenders. History Kiama was the site of two strong volcanic flows, called the Gerringong Volcanics, which came out of Saddleback Mountain, now a collapsed volcanic vent. The Kiama Blowhole is part of an erosion process on the more recent rock, formed into columnar basalt, or latite. Before the cedar-getters (comprising ex-convicts, convicts and runaways, some with cedar licences and many without) arrived in the area around 1810, the local Indigenous Australians, Wodi Wodi of the language group Dharawal, had been using the land for thousands of years, moving every six weeks or so in family groups. This is supported by a midden of shells ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Non-marine Molluscs Of Australia
This is a very incomplete list of the non-marine molluscs of the country of Australia. They are part of the invertebrate fauna of Australia. Freshwater gastropods The freshwater molluscs of Australia vary greatly in size, shape, biology and evolutionary history, and more than 99% of the native species occur nowhere else on earth. Currently, there are more than 400 native described species and a further 100 species that are undescribed.

George Masters
George Masters (1837-1912) was a zoologist, active in Australia during the 19th century. Biography Born in Maidstone, England, to Matilda, née Terry, he was trained as a gardener by his father, George Masters, before moving to Sydney. Masters began working as a gardener, then collecting insects in Queensland for William John Macleay, with the backing of the zoologist Gerard Krefft, later taking a position with the Australian Museum as an assistant curator. Works George Masters was a zoölogical collector, primarily of birds, but also of snakes and other animals. Masters also made a significant contribution to entomology, making large collections of insects available for research. He journeyed to remote regions to obtain specimens, including some that will difficult to obtain and are now listed as rare or endangered. His expeditions across the eastern states were extended to South and Western Australia, Tasmania, and Lord Howe Island. Noted collections include a series of speci ...

Malacologist
Malacology is the branch of invertebrate zoology that deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells. One division of malacology, conchology, is devoted to the study of mollusk shells. Malacology derives . Fields within malacological research include taxonomy, ecology Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi ... and evolution. Applied malacology studies medical, veterinary, and agricultural applications; for example, mollusks as vectors of disease, as in schistosomiasis. Archaeology employs malacology to understand the evolution of the climate, the biota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusc
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 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 phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and 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 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod
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.

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.
