Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
In taxonomy, binomial nomenclature, also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name, a binomen, binominal name, or a scientific name; more informally it is also historically called a Latin name. In the ICZN, the system is also called binominal nomenclature, "binomi'N'al" with an "N" before the "al", which is not a typographic error, meaning "two-name naming system".
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature. The rules principally regulate:
Orioles are colourful Old World passerine birds in the genus Oriolus, the type genus of the corvoidean family Oriolidae. They are not closely related to the New World orioles, which are icterids that belong to the superfamily Passeroidea.
Sirenidae, the sirens, are a family of neotenic aquatic salamanders. Family members have very small fore limbs and lack hind limbs altogether. In one species, the skeleton in their fore limbs is made of only cartilage. In contrast to most other salamanders, they have external gills bunched together on the neck in both larval and adult states. Sirens are found only in the Southeastern United States and northern Mexico.
The stork-billed kingfisher, is a tree kingfisher which is widely but sparsely distributed in the tropical Indian subcontinent and Southeast Asia, from India to Indonesia. This kingfisher is resident throughout its range.
The greater siren is an amphibian and one of the three members of the genus Siren. The largest of the sirens and one of the largest amphibians in North America, the greater siren resides in the coastal plains of the southeastern United States.
The green imperial pigeon is a large forest pigeon. The large range extends from Nepal, southern India and Sri Lanka eastwards to southern China, Indonesia and the Philippines.
The white-winged snowfinch, or snowfinch, is a small passerine bird. Despite its name, it is a sparrow rather than a true finch.
The two-toed amphiuma is an aquatic salamander widely distributed in the southeastern United States. It is commonly, but incorrectly, called "congo snake", "conger eel" or the "blind eel".
Alexander Garden FRSE FRS was a Scottish physician, botanist and zoologist. The gardenia flower is named after him. He lived for many years in Charleston, South Carolina, using his spare time to study plants and living creatures, and sending specimens to Carl Linnaeus.
The lesser siren is a species of aquatic salamander native to the eastern United States and northern Mexico. They are referred to by numerous common names, including two-legged eel, dwarf siren, and mud eel. The specific epithet intermedia denotes their intermediate size, between the greater siren, Siren lacertina, and the dwarf sirens, Pseudobranchus species.
The Cape batis is a small, stout insect-eating passerine bird in the wattle-eye family. It is endemic to the Afromontane forests of southern Africa.
The black-faced munia is a species of estrildid finch found in Indonesia and East Timor. It occurs in a wide range of habitats including artificial landscapes, forest, grassland and savannah. It was first described by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae in 1766. The IUCN has evaluated the status of this bird as being of least concern.
The Caribbean elaenia is a species of bird in the family Tyrannidae found in the West Indies and parts of Central America. Its natural habitats are tropical and subtropical dry broadleaf forest, subtropical or tropical moist lowland forest, and heavily degraded former forest.
The lesser Antillean bullfinch is a species of bird in the family Thraupidae. It is found in Saint Barth, Saint Martin, Anguilla, Antigua and Barbuda, Dominica, Grenada, Guadeloupe, Martinique, Montserrat, Netherlands Antilles, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, the British Virgin Islands, and the U.S. Virgin Islands.
In the 10th edition of Systema Naturae, published in 1758, the Swedish naturalist Carl Linnaeus described 554 species of bird and gave each a binomial name.
The reticulated siren, also known as the leopard siren or colloquially as the leopard eel, is a species of aquatic salamander in the family Sirenidae. The species, which is endemic to the southeastern United States, was first formally described in 2018. This cryptic salamander is known only from three localities in southern Alabama and the Florida panhandle and is one of the largest animals in the United States to be newly described in the past 100 years.
