Achatinellidae
Achatinellidae is a family of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Pupilloidea. Taxonomy It was previously the only family in the superfamily Achatinelloidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). It is now classified under the superfamily Pupilloidea. The family Achatinellidae represents a diverse adaptive radiation. All species of tree-snail in Hawaii are believed to have come from a single ancestral snail. How that ancestral snail made the trip across the ocean is unknown. A longstanding theory is that a bird carried a notably smaller ancestor across the ocean and dropped it on the islands, as bird mediated dispersal has been documented in other snail species. Alternative theories include that it floating across the ocean on a mat of debris, or that it island hopped across the Pacific in a combination of the theories. Subfamilies in the family Achatinellidae include: * Achat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achatinella
''Achatinella'' is a tropical genus of colorful land snails in the monotypic Achatinellidae subfamily Achatinellinae. Species are arboreal pulmonate gastropod mollusks with some species called Oʻahu tree snails or kāhuli in the Hawaiian language. ''Achatinella'' species are all endemic to the island of Oahu in Hawaii, and all remaining extant species are endangered. They were once abundant and were mentioned extensively in Hawaiian folklore and songs, and their shells were used in lei and other ornaments. Many of the species are sinistral or left-handed chirality in their spiral shell coiling, whereas most gastropod shells are dextral, with a right handed spiral. Distribution There were 41 species of ''Achatinella'' endemic to the Hawaiian island of Oʻahu, though only 13 species survive. Some species have less than 50 remaining individuals, and others have +300; many species fall in between. Conservation status All 13 species are listed under United States federal ...

Pupilloidea
Pupilloidea is a superfamily of small and very small air-breathing land snails, terrestrial gastropods in the infraorder '' Pupilloidei''. They are diverse in morphology, habitat, and ecological roles. Description They are characterized by their small, often cylindrical, ovate, or elongate shells. Their shells can range from smooth to ribbed or striated. They are generally tiny, ranging from a few millimeters to about a centimeter in length. The aperture often has denticles (teeth) or lamellae, which may play roles in predator deterrence or structural support. The margin of the aperture often features a well-defined peristome, sometimes thickened or reflected. Distribution Species in this superfamily are cosmopolitan, found on every continent except Antarctica. They can be found in dry and arid regions to temperate forests and even tropical zones. Taxonomy This superfamily contains the following families: * Achatinellidae Gulick, 1873 * Agardhiellidae Harl & Páll-Gergely, 2 ...

Yoshio Kondo
Yoshio Kondo (1910, on Maui, Hawaii - 1990, on Oahu, Hawaii) was an American biologist and malacologist. He spent virtually his entire life in Hawaii, with the exception of a number of collecting expeditions, primarily to islands in the Pacific Ocean (including the Mangarevan Expedition in 1934). Kondo had been trained as an electrician and was the chief engineer aboard the ''Myojin Maru'' at the time the boat was chartered for Bishop Museum's Mangarevan Expedition. Dr Cooke, the leader of the expedition, had been impressed by Kondo's interest in land shells that he was later hired as Assistant Malacologist at the museum. Kondo later enrolled at University of Hawai'i and received his Bachelor of Arts degree with honors. He then studied at Harvard University, where he received a Ph.D. under the direction of William J. Clench in 1955. He was known to most people as "Yoshi". Kondo spent his entire career, over 40 years, at the Bernice P. Bishop Museum in Honolulu. He was a Malacol ...

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 ...

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 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.

Mollusc
Mollusca is a phylum of protostome, protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant taxon, extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and 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. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater mollusc, freshwater and even terrestrial molluscs, terrestrial species. 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, neurologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur William Baden Powell
Arthur William Baden Powell (4 April 1901 – 1 July 1987) was a New Zealand malacologist, naturalist and palaeontologist, a major influence in the study and classification of New Zealand molluscs through much of the 20th century. He was known to his friends and family by his third name, "Baden". Biography Early life The name Baden had been a given name in a Powell family since 1731, when Susannah Powell née Thistlethwayte (1696–1762) gave to her child (1731–1792) the maiden name of her mother, Susannah Baden (1663–1692). The name Baden, particularly when associated with the surname Powell, became famous in 1900–1901, the year Arthur William Baden Powell was born, because of the siege of Mafeking, the most famous British action in the Second Boer War, which turned the British commander of the besieged, Robert Baden-Powell, into a national hero. Throughout the British Empire, babies were named after him. No family connection has yet been established between Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
