Fritz Haas
Fritz Haas (January 4, 1886 – December 26, 1969 in Hollywood, Florida) was a Jewish German zoologist born in Frankfurt am Main. He specialized in the field of malacology. He was trained in biology by herpetologist Oskar Boettger (1844–1910) and malacologist Wilhelm Kobelt (1840–1916). From 1911 to 1936, he was a curator of invertebrate zoology at the Senckenberg Museum in Frankfurt am Main. On June 30, 1936, the Nazis removed him from his position at the Senckenberg Museum. Fleeing Germany, Haas was appointed as the first curator of the new department of lower invertebrates (now the Division of Invertebrates) at the Field Museum of Natural History in Chicago, a position he retained until 1959. He identified and cataloged specimens that had lain unexamnied since the 1893 World Columbian Exposition, starting to build the museum's now world-class collection of aquatic invertebrates. Haas' specialty involved the study of land and freshwater snails, as well as research of the fami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Tree Snail
Tree snail is a common name that is applied to various kinds of tropical air-breathing land snails, pulmonate gastropod mollusks that have shells, and that live in trees, in other words, are exclusively arboreal in habitat. Some other species of air-breathing land snails may sometimes be found on tree trunks, or even in the foliage of trees, but this does not mean they live their whole lives in trees, and they are not considered to be tree snails. Tree snail Genera and species that have the words "tree snail" as a part of their common name include: forestry and silviculture are a part of the tree snails habitat * genus ''Achatinella'' - O'ahu tree snail, 40 species. * '' Partula'' - various species in the genus ''Partula'' are known under the common name "Moorean Viviparous Tree Snail" or "Polynesian Tree Snail". * ''Samoana'' - in addition, various species in the genus ''Samoana'' are known under the common name "Moorean Viviparous Tree Snail" or "Polynesian Tree Snail". ** ''S ...

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.

Mollusk
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.

Camaenidae
Camaenidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea, the typical snails and their allies. This is one of the most diverse families in the clade Stylommatophora. These snails occur in a wide variety of habitats in the tropics of Eastern Asia and Australasia. A large American group, which is mainly represented by species from the Caribbean, has, until recently, also been subsumed under the Camaenidae. However, latest molecular phylogenetic studies showed that these species represent a different family, the Pleurodontidae. This molecular study also implies that the Bradybaeninae, previously being treated as a distinct family within the Helicoidea, is a junior synonym of the Camaenidae. Anatomy Camaenid shells are often quite large (25–50 mm), but a number of species also have small shells (<5 mm). Shells reveal a remarkable diversity in shape and colour, which is partly linked with their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Vietnam
Central Vietnam ( vi, Trung Bộ or ), also known as Middle Vietnam or The Middle, formerly known as by South Vietnam, and Annam under French Indochina, is one of the three geographical regions within Vietnam. The name Trung Bộ was used by the king Bảo Đại when he established administrative level higher than Province in 1945, instead of the Trung Kỳ which recalled the French occupation. This name was officially used by government of the Democratic Republic of Vietnam and is popularly used today. Administration Central Vietnam includes 3 administrative regions, which in turn comprises 19 First Tier units. Municipality A municipality is usually a single administrative division having corporate status and powers of self-government or jurisdiction as granted by national and regional laws to which it is subordinate. The term ''municipality'' may also mean the go ... (thành phố trực thuộc trung ương) Of all 19 First Tier units, 1 is municipality and 18 are ...

Amphidromus
''Amphidromus'' is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Camaenidae. The shells of ''Amphidromus'' are relatively large, from to in maximum dimension, and particularly colorful. During the 18th century, they were among the first Indonesian land snail shells brought to Europe by travelers and explorers. Since then, the genus has been extensively studied: several comprehensive monographs and catalogs were authored by naturalists and zoologists during the time period from the early 19th to the mid 20th centuries. Modern studies have focused on better understanding the evolutionary relationships within the group, as well as solving taxonomic problems. The genus ''Amphidromus'' is unusual in that it includes species that have dextral shell-coiling and species that have sinistral shell-coiling. In addition, some species within this genus are particularly notable because their populations simultaneously include indivi ...
