Spondylurus Powelli
''Spondylurus powelli'', the Anguilla Bank skink, is a species of lizard belonging to the family Scincidae, the skinks. This species is found on some islands in the northern Lesser Antilles, the main ones being Anguilla and Saint Barthélemy, but it is not found on the main island of Saint Martin. Taxonomy ''Spondylurus powelli'' was first formally described in 2012 by the American biologists S. Blair Hedges and Caitlin Conn with its type locality given as Shannon Hill, north of Sandy Ground, Anguilla, the holotype being collected in 1963 by James D. "Skip" Lazell. Hedges and Conn also mention paratypes collected on Anguilla and St. Barts. This species, and '' S. martinae'', of the island of Saint Martin. form the ''S. martinae'' species group within the genus ''Spondylurus'', which is classified in the subfamily Mabuyinae of the skink family Scincidae. Etymology ''Spondylurus powelli'' is a member of the genus ''Spondylurus''. This name was coined by the Austrian zoolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species Group
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant variety (botany), varieties), which may be a complex ranking but it is not a species complex. In most cases, a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herpetologist
Herpetology (from Ancient Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is a branch of zoology concerned with the study of amphibians (including frogs, salamanders, and caecilians (Gymnophiona)) and reptiles (including snakes, lizards, turtles, crocodilians, and tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the separate scientific study of birds is the subject of ornithology. The precise definition of herpetology is the study of ectothermic (cold-blooded) tetrapods. This definition of "herps" (otherwise called "herptiles" or "herpetofauna") excludes fish; however, it is not uncommon for herpetological and ichthyological scientific societies to collaborate. For instance, groups such as the American Society of Ichthyologists and Herpetologists have co-published journals and hosted conferences to foster the exchange of ideas between the fields. Herpetological societies are formed to pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Type Species
In International_Code_of_Zoological_Nomenclature, 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 (biology), type wiktionary:en:specimen, specimen (or specimens). 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 International Code of Nomenclature for algae, fungi, and plants, 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 with 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 suc ...

Spondylurus Sloanii
''Spondylurus sloanii'', also known commonly as Sloane's skink or the Virgin Islands bronze skink, is a species of lizard in the family Scincidae. The species is native to the United States Virgin Islands and the British Virgin Islands. Etymology The specific name, ''sloanii'', is in honor of British naturalist Hans Sloane. Beolens B, Watkins M, Grayson M (2011). ''The Eponym Dictionary of Reptiles''. Baltimore, Maryland: Johns Hopkins University Press. xiii + 296 pp. . (''Mabuya sloanii'', p. 246). Habitat The preferred natural habitats of ''S. sloanii'' are the intertidal zone and shrubland.

Vertebra
Each vertebra (: vertebrae) is an irregular bone with a complex structure composed of bone and some hyaline cartilage, that make up the vertebral column or spine, of vertebrates. The proportions of the vertebrae differ according to their spinal segment and the particular species. The basic configuration of a vertebra varies; the vertebral body (also ''centrum'') is of bone and bears the load of the vertebral column. The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles (pedicle of vertebral arch), two laminae, and seven processes. The laminae give attachment to the ligamenta flava (ligaments of the spine). There are vertebral notches formed from the shape of the pedicles, which form the intervertebral foramina when the vertebrae articulate. These foramina are the entry and exit conduits for the spinal nerves. The body of the vertebr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopold Fitzinger
Leopold Joseph Franz Johann Fitzinger (13 April 1802 – 20 September 1884) was an Austrian zoologist. Fitzinger was born in Vienna and studied botany at the University of Vienna under Nikolaus Joseph von Jacquin. He worked at the Vienna Naturhistorisches Museum between 1817, when he joined as a volunteer assistant, and 1821, when he left to become secretary to the provincial legislature of Lower Austria; after a hiatus, he was appointed assistant curator in 1844 and remained at the Naturhistorisches Museum until 1861. Later, he became director of the zoos of Munich and Budapest. In 1826, he published ''Neue Classification der Reptilien'', based partly on the work of his friends Friedrich Wilhelm Hemprich and Heinrich Boie. In 1843, he published ''Systema Reptilium'', covering geckos, chameleons and iguanas. Fitzinger is commemorated in the scientific names of five reptiles: ''Algyroides fitzingeri'', ''Leptotyphlops fitzingeri'', ''Liolaemus fitzingerii'', ''Micrurus tener, Micr ...

Zoologist
Zoology ( , ) is the scientific study of animals. Its studies include the structure, embryology, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. Zoology is one of the primary branches of biology. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and used this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. Modern zoology has its origins during the Renaissance and early modern period, with Carl Linnaeus, Antonie van Leeuwenhoek, Robert Hooke, Charles Darwin, Gregor Mendel and many others. The study of animals has largely mov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skink
Skinks are a type of lizard belonging to the family (biology), family Scincidae, a family in the Taxonomic rank, infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions. Etymology The word ''skink'', which entered the English language around 1580–1590, comes from classical Greek and Latin , names that referred to various specific lizards. Description Skinks look like lizards of the family Lacertidae (sometimes called ''true lizards''), but most species of skinks have no pronounced neck and relatively small legs. Several genera (e.g., ''Typhlosaurus'') have no limbs at all. This is not true for all skinks, however, as some species such as the Tribolonotus gracilis, red-eyed crocodile skink have a head that is ve ...

Mabuyinae
Mabuyinae is a subfamily of lizards, commonly known as skinks, within the family Scincidae. The genera in this subfamily were previously found to belong the '' Mabuya'' group in the large subfamily Lygosominae. They have a pantropical distribution, being found throughout the tropics of Asia, Africa, and the Americas (but excluding most of Australasia aside from '' Eutropis multifasciata'', found in New Guinea). Although originating in and having most species in the Old World, they managed to colonize the Americas in the Miocene; the common ancestor of the American genera is thought to have rafted across the Atlantic from Africa to South America about 18 million years ago, with the skinks diversifying across the Americas and evolving into many new genera. Six genera ('' Alinea, Capitellum'', '' Copeoglossum'', '' Mabuya'', '' Marisora'', '' Spondylurus'') are found in the Caribbean The Caribbean ( , ; ; ; ) is a region in the middle of the Americas centered around the ...
