Oreella is a genus of tardigrades in the family Oreellidae. It is the only genus of that family. It was named and described by James Murray in 1920; the family Oreellidae was named and described by Giuseppe Ramazzotti in 1962. [1]

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. 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.

Tardigrade Phylum of animals

Tardigrades are a phylum of water-dwelling, eight-legged, segmented micro-animals. They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who gave them the name of "little water bears". The name Tardigrada was given in 1777 by the Italian biologist Lazzaro Spallanzani. They have been found everywhere: from mountaintops to the deep sea and mud volcanoes; from tropical rain forests to the Antarctic. Tardigrades are among the most resilient known animals, with individual species able to survive extreme conditions that would be rapidly fatal to nearly all other known life forms, such as exposure to extreme temperatures, extreme pressures, air deprivation, radiation, dehydration, and starvation. Tardigrades have even survived exposure to outer space. About 1,150 known species form the phylum Tardigrada, a part of the superphylum Ecdysozoa. The group includes fossils dating from 530 million years ago, in the Cambrian period.

Vespertilionidae family of vesper bats

Vespertilionidae is a family of micro-bats, of the order Chiroptera, flying insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat genera, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tail of the species are enclosed by the lower flight membranes between the legs, Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed as evening bats and once referred to as 'evening birds'.

Leaf warbler genus of birds

Leaf warblers are small insectivorous passerine birds belonging to the genus Phylloscopus. The genus was introduced by the German zoologist Friedrich Boie in 1826. The name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker".

Elopiformes order of fishes

The Elopiformes are the order of ray-finned fish including the tarpons, tenpounders, and ladyfish, as well as a number of extinct types. They have a long fossil record, easily distinguished from other fishes by the presence of an additional set of bones in the throat.

<i>Chamaecyparis</i> genus of plants

Chamaecyparis, common names cypress or false cypress, is a genus of conifers in the cypress family Cupressaceae, native to eastern Asia and to the western and eastern margins of the United States. The name is derived from the Greek khamai, meaning ground, and kuparissos for cypress.

Type species term used in zoological nomenclature (also non-officially in botanical nomenclature)

In zoological nomenclature, a type species 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). A similar concept is used for suprageneric groups called a type genus.

<i>Boronia</i> genus of plants

Boronia is a genus of about 160 species of flowering plants in the citrus family Rutaceae, most are endemic in Australia with a few species in New Caledonia, which were previously placed in the genus Boronella. They occur in all Australian states but the genus is under review and a number of species are yet to be described or the description published. Boronias are similar to familiar plants in the genera Zieria, Eriostemon and Correa but can be distinguished from them by the number of petals or stamens. Some species have a distinctive fragrance and are popular garden plants.

Taipan genus of reptiles

The taipans are snakes of the genus Oxyuranus in the elapid family. They are large, fast-moving, highly venomous, and endemic to Australasia. There are currently three recognised species, one of which, the coastal taipan, has two subspecies. The taipans are considered some of the most deadly known snakes.

<i>Eugenia</i> genus of plants

Eugenia is a genus of flowering plants in the myrtle family Myrtaceae. It has a worldwide, although highly uneven, distribution in tropical and subtropical regions. The bulk of the approximately 1,100 species occur in the New World tropics, especially in the northern Andes, the Caribbean, and the Atlantic Forest of eastern Brazil. Other centers of diversity include New Caledonia and Madagascar.

Taxonomic rank Level in a taxonomic hierarchy

In biological classification, taxonomic rank is the relative level of a group of organisms in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc.

<i>Pityrodia</i> genus of plants

Pityrodia is a genus of flowering plants in the mint family, Lamiaceae and is endemic to Australia, most species occurring in Western Australia, a few in the Northern Territory and one in Queensland. Plants in this genus are shrubs with five petals joined to form a tube-shaped flower with four stamens of unequal lengths.
