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.
Columbidae is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms.
Galeocerdo is a genus of ground shark. Only a single species, G. cuvier, the tiger shark is extant. The earliest fossils date back to the early Eocene epoch, (Ypresian), around 56–47.8 Million years ago. While historically considered a member of the requiem shark family Carcharhinidae, it is currently considered to be the only member of the family Galeocerdonidae. While this genus was historically considered diverse, including 21 extinct species, morphometric analysis conducted in 2021 suggested that the diversity of the genus included only 5 extinct species much lower than previously assumed. The oldest fossils of the extant G. cuvier date to the middle Miocene.
Inia is a genus of river dolphins from South America containing one to four species.
The yellow-headed blackbird is a medium-sized blackbird with a yellow head.
The vesper sparrow is a medium-sized New World sparrow. It is the only member of the genus Pooecetes.
Pyracantha is a genus of large, thorny evergreen shrubs in the family Rosaceae, with common names firethorn or pyracantha. They are native to an area extending from Southwest Europe east to Southeast Asia. They resemble and are related to Cotoneaster, but have serrated leaf margins and numerous thorns.
Adansonia is a genus made up of eight species of medium-to-large deciduous trees known as baobabs. They are placed in the Malvaceae family, subfamily Bombacoideae. They are native to Madagascar, mainland Africa, and Australia. The trees have also been introduced to other regions such as Asia. The generic name honours Michel Adanson, the French naturalist and explorer who described Adansonia digitata. The baobab is also known as the "upside down tree", a name that originates from several myths. They are among the most long-lived of vascular plants and have large flowers that are reproductive for a maximum of 15 hours. The flowers open around dusk, opening so quickly that movement can be detected by the naked eye, and are faded by the next morning. The fruits are large, oval to round and berry-like and hold kidney-shaped seeds in a dry, pulpy matrix.
Turbonillinae is a subfamily of mostly minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.
The Sulawesi forest turtle is a critically endangered species of turtle in the family Geoemydidae. The species is monotypic within the genus Leucocephalon. It is endemic to Sulawesi in Indonesia.
Enidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks.
Chelonoidis is a genus of turtles in the tortoise family erected by Leopold Fitzinger in 1835. They are found in South America and the Galápagos Islands, and formerly had a wide distribution in the West Indies.
Euphronia is a genus of three species of shrubs native to northern South America and is the only genus in the family Euphroniaceae. It was previously classified in the Vochysiaceae family and elsewhere due to its unique floral features, but the APG III system of 2009 recognized Euphroniaceae as distinct and placed Euphronia in it. Based on molecular data from the rbcL gene, it is sister to the Chrysobalanaceae.
Kejdonia is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Heterocyathus is a genus of coral of the family Caryophylliidae.
