Boa Constrictor
The boa constrictor (scientific name also ''Boa constrictor''), also called the red-tailed boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity. The boa constrictor is a member of the family Boidae, found in tropical South America, as well as some islands in the Caribbean. A staple of private collections and public displays, its color pattern is highly variable yet distinctive. Four subspecies are currently recognized. This article focuses on the species ''Boa constrictor'' as a whole, and on the nominate subspecies ''B. c. constrictor''. Common names Though all boids are constrictors, only this species is properly referred to as a "boa constrictor"—a rare instance of an animal having the same common English name and scientific binomial name. All subspecies are referred to as "boa constrictors", and are part of a diverse group of New World boas referred to as "red-tailed" boas, comprising species of both ''Boa constrict ...

Boa Sigma
''Boa sigma'', known commonly as the Mexican west coast boa constrictor, is a species of snake in the family Boidae. The species is endemic to western Mexico. ''Boa sigma'' has previously been regarded as conspecific with ''Boa constrictor'', and later with '' Boa imperator''; however, in 2016, it was suggested on genetic grounds that ''Boa sigma'' should be regarded as a separate species. Taxonomy ''Boa sigma'' was originally described as ''Constrictor constrictor sigma'' by Hobart Muir Smith in 1943. The subspecies only included snakes from the Islas Marías, and it didn't receive wide recognition; instead, it was synonymized with the mainland subspecies ''Boa constrictor imperator'' by many authors. In the 21st century, genetic studies revealed that ''Boa constrictor'' is a species complex. First, ''Boa constrictor imperator'' was elevated to species level, but it was soon recognized that there was another species nested within the new ''Boa imperator''. According to Card et ...

Boa Constrictor Occidentalis
''Boa constrictor occidentalis'', also commonly known as the Argentine boa, is a subspecies of large, heavy-bodied, nonvenomous, constricting snake. ''Boa constrictor occidentalis'' is a member of the family Boidae, found in the subtropical temperate west of Argentina and Paraguay, although some members have been reported to exist in Bolivia as well. Description Size and weight The ''Boa constrictor occidentalis'' subspecies experiences sexual dimorphism, with females being greater in size and weight. Adult males reach anywhere between 6 and 8 feet. Whereas adult females can reach lengths of 8 to 10 feet regularly, though some members have been found to reach as long as 4 m (13.13 ft). Male members of this subspecies on average weigh 4.06 kg (8.95 lb). Female members are much heavier, weighing at an average of 6.13 kg (13.5 lb). Male Argentine boas generally have longer tails in order to contain the hemipenes as well as having longer pelvic sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constriction
Constriction is a method used by various snake species to kill or subdue their prey. Although some species of venomous and mildly venomous snakes do use constriction to subdue their prey, most snakes which use constriction lack venom. The snake initially strikes at its prey and holds on, pulling the prey into its coils or, in the case of very large prey, pulling itself onto the prey. The snake will then wrap one or two loops around the prey, forming a constriction coil. The snake will monitor the prey's heartbeat to ascertain when it is dead. This can be a physically demanding and potentially dangerous procedure for the snake, as it accelerates its metabolism up to seven times and leaves it vulnerable to attack by another predator. Contrary to myth, the snake does not crush the prey, or break its bones. However, several natural observations exist involving wild Anacondas that show broken bones in large prey. Also, contrary to previous belief, the snake does not cause suffocatio ... [...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 coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boa Imperator
''Boa imperator'' or ''Boa constrictor imperator'' (in common usage) is a large, heavy-bodied, nonvenomous species of snake, of the boa genus, that is commonly kept in captivity. ''Boa imperator'' is part of the family Boidae and is found in Mexico, Central America and South America west of the Andes Mountains (primarily Colombia). It is commonly called the common boa, northern boa, Colombian boa and common northern boa and is frequently and erroneously referred to as the red-tailed boa or Colombian red-tailed boa, especially in the pet trade. Description ''Boa imperator'' is wide-ranging, with animals living in both Central America and northern parts of South America. As a result, the appearance of this snake varies greatly depending on the specific locality. As one of the smaller '' Boa'' species, Wild caught specimens will often contain parasites, both internal and external. The most common parasite is ''Ophionyssus natricis'' or the "reptile mite".

Reticulated Python
The reticulated python (''Malayopython reticulatus'') is a python species native to South and Southeast Asia. It is the world's longest snake, and is among the three heaviest. It is listed as least concern on the IUCN Red List because of its wide distribution. In several countries in its range, it is hunted for its skin, for use in traditional medicine, and for sale as pets. It is an excellent swimmer, has been reported far out at sea, and has colonized many small islands within its range. Like all pythons, it is a non-venomous constrictor. Adult humans have been killed (and in at least two reported cases, eaten) by reticulated pythons. Taxonomy The reticulated python was first described in 1801 by German naturalist Johann Gottlob Theaenus Schneider, who described two zoological specimens held by the Göttingen Museum in 1801 that differed slightly in colour and pattern as separate species—''Boa reticulata'' and ''Boa rhombeata''. The specific name, ''reticulatus'', is La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomists
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evol ...

Herpetologists
Herpetology (from Greek ἑρπετόν ''herpetón'', meaning " reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition "herps" (or sometimes "herptiles" or "herpetofauna") exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. Examples include publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields, as the American Society of Ichthyologists a ...

James Orton
James Orton (21 April 1830, Seneca Falls, New York – 25 September 1877, Lake Titicaca, Peru) was an American naturalist who contributed much to the knowledge of South America and the Amazon basin. Biography Orton was the son of Presbyterian clergyman and theologian Azariah Giles Orton. Four of his seven brothers died in infancy, and the family's financial resources were very meager. Early in life he developed an interest in natural history and writing. Financial difficulties and poor health delayed his matriculation at Williams College, where he graduated in 1855. In 1858, he graduated from Andover Theological Seminary. After spending some time in travel in Europe and the East, he was ordained pastor of the Congregational Church in Greene, New York, on July 11, 1860. In 1861 he accepted a charge in Thomaston, Maine, where he remained until 1864, when he became pastor in Brighton, New York. He was appointed instructor in natural sciences in the University of Rochester in 1866 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
