Przewalski's gerbil or Przewalski's jird (Brachiones przewalskii) is a species of rodent in the family Muridae. It is the only species in the genus Brachiones, and is found only in China.
Przewalski's horse also called the takhi, Mongolian wild horse or Dzungarian horse, is a rare and endangered horse originally native to the steppes of Central Asia. At one time extinct in the wild, it has been reintroduced to its native habitat since the 1990s in Mongolia at the Khustain Nuruu National Park, Takhin Tal Nature Reserve, and Khomiin Tal, as well as several other locales in Central Asia and Eastern Europe. The taxonomic position is still debated, with some taxonomists treating Przewalski's horse as a species, E. przewalskii, others as a subspecies of wild horse or a feral variety of the domesticated horse (E. f. caballus). It is named after the Russian geographer and explorer Nikołaj Przewalski.
Nikolay Mikhaylovich Przhevalsky was a Russian Imperial geographer and a renowned explorer of Central and East Asia.
Equus is a genus of mammals in the family Equidae, which includes horses, donkeys, and zebras. Within the Equidae, Equus is the only recognized extant genus, comprising seven living species. Like Equidae more broadly, Equus has numerous extinct species known only from fossils. The genus most likely originated in North America and spread quickly to the Old World. Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes, and long tails. All species are herbivorous, and mostly grazers, with simpler digestive systems than ruminants but able to subsist on lower-quality vegetation.
The wild horse is a species of the genus Equus, which includes as subspecies the modern domesticated horse as well as the undomesticated tarpan, and the endangered Przewalski's horse.
Equus lambei is an extinct species of the genus Equus. Equus lambei ranged across North America until approximately 10,000 years ago. Based on recent examinations of the mtDNA of Equus lambei remains, scientists have concluded that E. lambei was probably much like the extinct Tarpan, also known as the Eurasian wild horse, and the living Przewalski's Horse.[6][8] A partial carcass of Equus lambei is on display at the Yukon Beringia Interpretive Centre in Whitehorse, Yukon.
Przewalski's gazelle is a member of the family Bovidae, and in the wild, is found only in China. Once widespread, its range has declined to six populations near Qinghai Lake. The gazelle was named after Nikolai Przhevalsky, a Russian explorer who collected a specimen and brought it back to St. Petersburg in 1875.
The evolution of the horse, a mammal of the family Equidae, occurred over a geologic time scale of 50 million years, transforming the small, dog-sized, forest-dwelling Eohippus into the modern horse. Paleozoologists have been able to piece together a more complete outline of the evolutionary lineage of the modern horse than of any other animal. Much of this evolution took place in North America, where horses originated but became extinct about 10,000 years ago.
Eolagurus is a genus of rodent in the family Cricetidae. It contains the following species:
Przewalski's steppe lemming is a species of rodents in the family Cricetidae. It is found in China and Mongolia.
Juniperus przewalskii, or Przewalski's juniper, is a species of juniper native to the mountains of western China in Gansu, Qinghai, and northernmost Sichuan, growing at altitudes of 1,000-3,300 m.
Ligularia przewalskii (Maxim.) Diels, also called Przewalski's leopardplant and Przewalski's golden ray, is a species of 1.5–2 m (4.9–6.6 ft) tall perennial herbaceous plant in the genus Ligularia and the family Asteraceae, native to damp places in Mongolia and Northern China and named after Nikolai Przhevalsky. It used to be called Senecio przewalskii Maxim. Przewalski's Ligularia is a popular ornamental plant grown for its large, deeply cut foliage and its tall spike-like inflorescences with bright yellow composite flowers blooming from July to August.
Procapra is a genus of Asian gazelles, including three living species:
The history of horse domestication has been subject to much debate, with various competing hypotheses over time about how domestication of the horse occurred. The main point of contention was whether the domestication of the horse occurred once in a single domestication event, or that the horse was domesticated independently multiple times. The debate was resolved at the beginning of the 21st century using DNA evidence that favored a mixed model in which domestication of the stallion most likely occurred only once, while wild mares of various regions were included in local domesticated herds.
Gymnocypris przewalskii is a species of cyprinid that is endemic to the Lake Qinghai basin in China, where it is the dominant fish species. G. przewalskii is a planktivore with a main population that migrates from the lake to rivers to spawn and another that lives its entire life in the nearby Ganzi River. The species is listed as endangered on the China Species Red List due to overfishing and habitat loss, which has led to suspension of its commercial fishery four times since 1989.

Przevalski's nuthatch, originally given the nomen nudum"Sitta eckloni", is a bird species in the family Sittidae, collectively known as nuthatches. Long regarded as a subspecies of the white-cheeked nuthatch, it nevertheless differs significantly in morphology and vocalizations. Both S. przewalskii and S. leucopsis have been regarded as closely related to the North American white-breasted nuthatch. It is a medium-sized nuthatch, measuring about 13 cm (5 in) in length. Its upper body is a dark gray-blue or slate color, becoming dark blue-black at the crown. The cheeks and throat are a white buff-orange, turning to a rich cinnamon on the underparts that intensifies in color on the sides of the breast. Vocalizations consist of alternating series of ascending whistles and short notes.
Hypericum przewalskii, commonly called Przewalski's St. John's wort, is a flowering plant in Hypericumsect. Roscyna that is native to China.
Przewalski's wonder gecko is a species of lizard in the family Sphaerodactylidae. The species is endemic to East Asia.
Eremias przewalskii, commonly known as the Gobi racerunner, is a species of lizard in the family Lacertidae. The species is endemic to Asia.
Phrynocephalus przewalskii, Przewalski's toadhead agama, Tsarewsky's toadhead agama, or Steindachner's toadhead agama, is a species of agamid lizard found in China and Mongolia.
