Leptestheriidae
Leptestheriidae is a family of crustaceans in the order Spinicaudata. They are distinguished from the family Cyzicidae by the presence of a rostral spine. Members of Leptestheriidae are believed to graze on detritus. The family contains five extant genera: * ''Eoleptestheria ''Eoleptestheria ticinensis'' is a species of clam shrimp in the family Leptestheriidae. Although up to eight species have formerly been recognised in the genus ''Eoleptestheria'', they are more usually all considered part of one species with a ...'' * '' Leptestheria'' *: '' Leptestheria compleximanus'' * '' Leptestheriella'' * '' Maghrebestheria'' * '' Sewellestheria'' References Spinicaudata Crustacean families {{branchiopoda-stub ...

Eoleptestheria
''Eoleptestheria ticinensis'' is a species of clam shrimp in the family Leptestheriidae. Although up to eight species have formerly been recognised in the genus ''Eoleptestheria'', they are more usually all considered part of one species with a cosmopolitan distribution In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and en ....

Cyzicidae
Cyzicidae is a family of crustaceans in the order Spinicaudata. They are distinguished from the family Leptestheriidae by the absence of a rostral spine. Some members of Cyzicidae are known to burrow through mud, leading to speculation that they may be filter feeders, but Martin reports that their mouthparts are indistinguishable from Leptestheriidae, which are believed to be grazers. The family contains four extant genera: * '' Caenestheria'' * '' Caenestheriella'' * ''Cyzicus Cyzicus ( ; ; ) was an ancient Greek town in Mysia in Anatolia in the current Balıkesir Province of Turkey. It was located on the shoreward side of the present Kapıdağ Peninsula (the classical Arctonnesus), a tombolo which is said to have or ...'' * '' Eocyzicus'' References Spinicaudata Crustacean families {{branchiopoda-stub ...

Spinicaudata
Clam shrimp are a group of bivalved branchiopod crustaceans that resemble the unrelated bivalved molluscs. They are extant and also known from the fossil record, from at least the Devonian period and perhaps before. They were originally classified in the former order Conchostraca, which later proved to be paraphyletic, because water fleas are nested within clam shrimps. Clam shrimp are now divided into three orders, Cyclestherida, Laevicaudata, and Spinicaudata, in addition to the fossil family Leaiidae. Characteristics Both valves of the shell are held together by a strong closing muscle. The animals react to danger by contracting the muscle, so that the valves close tightly and the crustacean, as if dead, lies motionlessly at the bottom of the pool. In most species the head is dorsoventrally compressed. The sessile compound eyes are close together and located on the forehead; in the genus ''Cyclestheria'' they are truly fused. In front of them is a simple naupliar eye. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eugen Von Daday
Eugen von Daday or Jenő von Daday (1855–1920) was an ethnic Romanian professor of zoology in Hungary in the late 19th and early 20th century. Daday was an expert on aquatic invertebrates, particularly crustaceans. Daday collected and identified many species and genera within the borders of the Hungarian empire, and received samples of invertebrates from collectors around the world. After his death in 1920, Daday's collection of crustaceans was acquired by the Hungarian Natural History Museum The Hungarian Natural History Museum () in Budapest, dating back to 1802, houses the largest natural history collections of Hungary and the region. History of the museum Foundation In 1802, Count Ferenc Széchényi offered his library and h ....

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Crustacean
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans ( oligostracans and multicrustaceans). The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomical Terms Of Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Leptestheria Compleximanus
''Leptestheria compleximanus'' is a species of North American clam shrimp known by the common name playa clam shrimp or spineynose clam shrimp. Range ''Leptestheria compleximanus'' is found from the Great Plains region of the United States to the deserts of northern Mexico. Habitat Playa clam shrimp live in temporary wetlands. Ecology Ephemeral wetland specialists, ''Leptestheria compleximanus'' depend on wet-dry cycles. Their life cycle has evolved to depend on drying to the point that all eggs they lay are desiccation-resistant and will not hatch during the same wet cycle during which adults are alive. These eggs will need to experience dry conditions followed by another inundation cycle to break diapause and hatch. While alive, playa clam shrimp feed on suspended particles through filter feeding Filter feeders are aquatic animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms (bacteria, microalgae and zooplanktons) sus ...
