Geophilus Electricus
''Geophilus electricus'' is a species of soil centipede in the family Geophilidae found across temperate Europe, especially Britain and Ireland. Originally discovered and named ''Scolopendra electrica'' in 1758, it was later moved to its own genus, Geophilus. As the first species described in this genus, it is considered by some to be the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen ... (along with '' Geophilus carpophagus''). It is yellowish-orange in color and can grow up to 45 millimeters, with 55 to 75 leg pairs (more than other similar ''Geophilus'' species), a distinct carpophagus fossae on the anterior sternites, and a distinctive arrangement of the coxal pores of the last leg pair. Like many geophilomorphans, ''G. electricus'' has been known to glow in the da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...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] |
Geophilomorpha
The centipedes or Chilopoda are divided into the following orders. Scutigeromorpha The Scutigeromorpha are anamorphic, reaching 15 leg-bearing segments in length. Also known as house centipedes, they are very fast creatures, and able to withstand falling at great speed: they reach up to 15 body lengths per second when dropped, surviving the fall. They are the only centipede group to retain their original compound eyes, within which a crystalline layer analogous to that seen in chelicerates and insects can be observed. They also bear long and multi-segmented antennae. Adaptation to a burrowing lifestyle has led to the degeneration of compound eyes in other orders; this feature is of great use in phylogenetic analysis. The group is the sole extant representative of the Notostigmophora, defined by having a single spiracle opening at the posterior of each dorsal plate. The more derived groups bear a plurality of spiracular openings on their sides, and are termed the Pleurostigmopho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Geophilidae
The Geophilidae are a polyphyletic, cosmopolitan family of soil centipedes in the superfamily Geophiloidea containing the mostly defunct clades Aphilodontidae, Dignathodontidae, Linotaeniidae, Chilenophilinae, and Macronicophilidae. Species in this family are characterized by mandibles with a single pectinate lamella, slender antennae, sternal pores with variable arrangement, a generally slightly or moderately elongate head, frequently undivided coxosternite with two paramedian sclerotized lines, claws without rows of filament, and female gonopods usually being an undivided lamina. Compared to most other families in the suborder Adesmata, this family features a modest number of leg-bearing segments (no more than 125) and limited variation in this number within each species. Two species in this family include centipedes with only 29 pairs of legs: ''Geophilus persephones'' (29 pairs in the only specimen, a male), and '' G. richardi'' (29 or 31 pairs in the males and 33 pairs in ...

Geophilus
''Geophilus '' is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with '' Brachygeophilus''. It is a mostly holarctic genus characterized by a claw-shaped ultimate pretarsus, anterior porefields, complete or nearly complete coxo-pleural sutures at the prosternum, and incomplete chitin-lines. The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as ''Geophilus electricus''. Although centipedes in this genus can have as many as 89 pairs of legs, most species have a much smaller number of leg pairs. For example, two species in this genus include centipedes with only 29 pairs of legs, the lowest number found in the family Geophilidae: '' G. persephones'' (29 pairs in the only specimen, a male) and '' G. richardi'' (29 or 31 pairs in males and 33 pairs in females). This genus also includes other species with notably few legs, for example, ''G. hadesi'' (33 pairs in both males and females) and ''G ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Geophilus Carpophagus
''Geophilus carpophagus'' is a species of soil centipede in the family Geophilidae, widely considered to be a type species of the genus ''Geophilus'' (along with '' G. electricus''). It grows up to 60 millimeters in length, with an orange/tan body bearing a distinctive purplish marbled pattern (also seen in '' Henia vesuviana''). Males of this species have 51 to 55 pairs of legs; females have 53 to 57. Taxonomy Recent studies indicate that ''G. carpophagus'' is actually a group of closely related species (dubbed the carpophagus species-complex). So far only three species have been clearly defined; ''G. carpophagus'' (Leach, 1814), '' G. easoni'' (Arthur, et al., 2001) from Europe, and '' G. arenarius'' (Meinert, 1870) from North Africa. Habitat ''Geophilus carpophagus'' is most commonly found across southeast England, though specimens have also been found in mainland Europe, North Africa, and the Canarie Islands, with a viable population discovered in Finland in 2018.

Synanthrope
A synanthrope (from the Greek σύν ''syn'', "together with" + ἄνθρωπος ''anthropos'', "man") is a member of a species of wild animal or plant that lives near, and benefits from, an association with human beings and the somewhat artificial habitats that people create around themselves (see anthropophilia). Such habitats include houses, gardens, farms, roadsides and rubbish dumps. The category of synanthrope includes many species regarded as pests or weeds. It does not, however, include domesticated animals such as cattle, honeybees, pets, poultry, silkworms, and working animals. Examples of synanthropes are various insect species ( lice, ants, silverfish, cockroaches, etc.), house sparrows, rock doves (pigeons), crows, various rodent species, Virginia opossums, raccoons, certain monkey species, coyotes, deer, urban ferals, passerines, and other urban wildlife. Plants include Pineapple Weed, Dandelion, Chicory, and Plantain. The brown rat is counted as one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
