Hoffman's Dwarf Centipede
''Nannarrup hoffmani'', commonly known as Hoffman's dwarf centipede, is a species of centipede that was discovered in New York City's Central Park in 2002. It is 10 mm long, and has 82 legs. Researchers think that the species originated in East Asia and was carried to the United States in a shipment of imported plants. The species is the first new species to be discovered in Central Park in more than a century. It is the smallest known species of centipede. The species is named after Dr. Richard L. Hoffman, former curator of invertebrates at the Virginia Museum of Natural History The Virginia Museum of Natural History is the state's natural history museum located in Martinsville, Virginia founded in 1984. The museum has several different award-winning publications, is affiliated with the Smithsonian Institution, and has ..., for his role in helping to identify the species.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Psammodesmus Bryophorus
The moss millipede (''Psammodesmus bryophorus'') is a keeled millipede of the family Platyrhacidae native to Colombia. It was described in 2011, and with several species of symbiotic moss found growing on its dorsal surface, it is the first millipede known with epizoic plants. At least 10 species of bryophytes belonging to families Pilotrichaceae, Lejeuneaceae, Fissidentaceae, Metzgeriaceae Metzgeriaceae is a family of thallose liverworts in the order Order, ORDER or Orders may refer to: * Categorization, the process in which ideas and objects are recognized, differentiated, and understood * Heterarchy, a system of organization w ... and Leucomiaceae have been found to grow on the millipede's dorsum; these plants are believed to camouflage the millipede as its cuticle provides a stable substrate.

Virginia General Assembly
The Virginia General Assembly is the legislative body of the Commonwealth of Virginia, the oldest continuous law-making body in the Western Hemisphere, the first elected legislative assembly in the New World, and was established on July 30, 1619. The General Assembly is a bicameral body consisting of a lower house, the Virginia House of Delegates, with 100 members, and an upper house, the Senate of Virginia, with 40 members. Combined, the General Assembly consists of 140 elected representatives from an equal number of constituent districts across the commonwealth. The House of Delegates is presided over by the Speaker of the House, while the Senate is presided over by the Lieutenant Governor of Virginia. The House and Senate each elect a clerk and sergeant-at-arms. The Senate of Virginia's clerk is known as the "Clerk of the Senate" (instead of as the "Secretary of the Senate", the title used by the U.S. Senate). Following the 2019 election, the Democratic Party held a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carilion Roanoke Memorial Hospital
Carilion Roanoke Memorial Hospital (CRMH) is a private teaching hospital in Roanoke, Virginia, USA. With 703 beds, Carilion Roanoke Memorial Hospital is one of the largest hospitals in the state. It is part of Carilion Clinic. The region's only level I trauma center, the hospital operates three medical helicopters (LifeGuard 10, 11, and 12) to provide air ambulance transport, including one in Moneta, one in Christiansburg, and one in Lexington. History The hospital was founded in 1899 as Roanoke Hospital. In the 1920s and 1930s, its growth was funded through gifts of hundreds of thousands of dollars from David W. Flickwir, a railroad executive and contractor who had married the hospital's nursing superintendent. The hospital dubbed him its "Greatest Benefactor"; a 1925 building he funded, the Flickwir Memorial Unit, still stands. In the 21st century, the hospital completed a large expansion project, adding an emergency department, a labor-and-delivery unit, and the Carilio ...

Invertebrate Zoology
Invertebrate zoology is the subdiscipline of zoology that consists of the study of invertebrates, animals without a backbone (a structure which is found only in fish, amphibians, reptiles, birds and mammals). Invertebrates are a vast and very diverse group of animals that includes sponges, echinoderms, tunicates, numerous different phyla of worms, molluscs, arthropods and many additional phyla. Single-celled organisms or protists are usually not included within the same group as invertebrates. Subdivisions Invertebrates represent 97% of all named animal species, and because of that fact, this subdivision of zoology has many further subdivisions, including but not limited to: *Arthropodology - the study of arthropods, which includes :*Arachnology - the study of spiders and other arachnids :* Entomology - the study of insects :*Carcinology - the study of crustaceans :*Myriapodology - the study of centipedes, millipedes, and other myriapods * Cnidariology - the study of Cnid ...

Crayfish
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as ''Procambarus clarkii'', are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' (Modern French '). The word has been modified to "crayfish" by association with "fish" (folk etymology). The largely American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commensalism
Commensalism is a long-term biological interaction (symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. This is in contrast with mutualism, in which both organisms benefit from each other; amensalism, where one is harmed while the other is unaffected; parasitism, where one is harmed and the other benefits, and parasitoidism, which is similar to parasitism but the parasitoid has a free-living state and instead of just harming its host, it eventually ends up killing it. The commensal (the species that benefits from the association) may obtain nutrients, shelter, support, or locomotion from the host species, which is substantially unaffected. The commensal relation is often between a larger host and a smaller commensal; the host organism is unmodified, whereas the commensal species may show great structural adaptation consistent with its habits, as in the remoras that ride attached to sharks and other fishes.

Oligochaete
Oligochaeta () is a subclass of animals in the phylum Annelida, which is made up of many types of aquatic and terrestrial worms, including all of the various earthworms. Specifically, oligochaetes comprise the terrestrial megadrile earthworms (some of which are semiaquatic or fully aquatic), and freshwater or semiterrestrial microdrile forms, including the tubificids, pot worms and ice worms (Enchytraeidae), blackworms (Lumbriculidae) and several interstitial marine worms. With around 10,000 known species, the Oligochaeta make up about half of the phylum Annelida. These worms usually have few setae (chaetae) or "bristles" on their outer body surfaces, and lack parapodia, unlike polychaeta. Diversity Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton. They range in length from less than up to in the 'giant' species such as the giant Gippsland earthworm (''Megascolides australis'') and the Mekong worm (''Amynthas meko ...
