Hamsters are rodents belonging to the subfamily Cricetinae, which contains 19 species classified in seven genera. They have become established as popular small pets. The best-known species of hamster is the golden or Syrian hamster, which is the type most commonly kept as a pet. Other hamster species commonly kept as pets are the three species of dwarf hamster, Campbell's dwarf hamster, the winter white dwarf hamster and the Roborovski hamster.
The golden hamster or Syrian hamster is a rodent belonging to the hamster subfamily, Cricetinae. Their natural geographical range is in an arid region of northern Syria and southern Turkey. Their numbers have been declining in the wild due to a loss of habitat from agriculture and deliberate elimination by humans. Thus, wild golden hamsters are now considered endangered by the International Union for Conservation of Nature. However, captive breeding programs are well established, and captive-bred golden hamsters are often kept as small house pets. They are also used as scientific research animals.
Campbell's dwarf hamster is a species of hamster in the genus Phodopus. It was given its common name by Oldfield Thomas in honor of Charles William Campbell, who collected the first specimen in Mongolia on July 1, 1902. It is distinguished from the closely related Djungarian hamster as it has smaller ears and no dark fur on its crown. Campbell's dwarf hamster typically has a narrow dorsal stripe compared to the Djungarian hamster and brown or gray fur on the stomach. This hamster may be raised in captivity and kept as a small pet.
Phodopus, a genus of rodents in the hamster subfamily Cricetinae—a division of the larger family Cricetidae—is a lineage of small hamsters native to central Asia that display unusual adaptations to extreme temperatures. They are the only known hamsters that live in groups and, in some cases, rely on significant contributions by males to the raising of offspring. They are nocturnal and active throughout the year; they do not hibernate. Species of Phodopus, together with members of the genera Cricetulus, Allocricetulus and Tscherskia are called dwarf hamsters because of their small size relative to other hamsters.
Hylomys is a small genus of the family Erinaceidae. Hylomys species, like all species in the subfamily Galericinae, are known as gymnures or moonrats. Their closest relatives include the fossil Lantanotherium and Thaiagymnura and the living Neotetracus and Neohylomys. Members of this genus are found in Southeast Asia and Eastern Asia.
The Chinese hamster is a rodent in the genus Cricetulus of the subfamily Cricetidae that originated in the deserts of northern China and Mongolia. They are distinguished by an uncommonly long tail in comparison to other hamsters, most of whose tails are stubby. Chinese hamsters are primarily nocturnal, however they will stay awake for brief periods, in between naps, throughout the day.
The Chinese striped hamster, also known as the striped dwarf hamster, is a species of hamster. It is distributed across North Asia from southern Siberia through Mongolia and northeastern China to northern North Korea. An adult Chinese striped hamster weighs 20 to 35 g, and has a body length of 72 to 116 mm with a tail of 15 to 26 mm. It is smaller and has a much shorter tail than the greater long-tailed hamster, Tscherskia triton, which inhabits much of the same range.
Suncus is a genus of shrews in the family Soricidae.
Meriones is a rodent genus that includes the gerbil most commonly kept as a pet, Meriones unguiculatus. The genus contains most animals referred to as jirds, but members of the genera Sekeetamys, Brachiones, and sometimes Pachyuromys are also known as jirds. The distribution of Meriones ranges from northern Africa to Mongolia. Meriones jirds tend to inhabit arid regions including clay desert, sandy desert, and steppe, but are also in slightly wetter regions, and are an agricultural pest.
Beamys is a genus of rodent in the family Nesomyidae. It contains the following species:
The Gansu hamster is a species of rodent in the family Cricetidae, endemic to China. It is the only species in the genus Cansumys.
The Tibetan dwarf hamster is a species of rodent in the family Cricetidae. It is found not only in Tibet and China, but also in India and Nepal in mountainous regions at altitudes of up to about 5,200 m (17,100 ft).
The Kam dwarf hamster is a species of rodent in the family Cricetidae. It is found only in the mountains of western China where it inhabits grassland, shrubby marshes and steppes. Although it has a limited range, the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The long-tailed dwarf hamster is a species of rodent in the family Cricetidae. It is found in China, Kazakhstan, Mongolia, and Russia.
The grey dwarf hamster, grey hamster or migratory hamster is a species of rodent in the family Cricetidae. Its range extends from Eastern Europe through the Middle East, Russia and Central Asia to Mongolia and western China. The grey dwarf hamster has grey fur and a head-body length ranging from 85 to 120 mm. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Sokolov's dwarf hamster is a species of rodent in the hamster and vole family Cricetidae. Previously listed as conspecific with Chinese striped hamster, it has been listed as a separate species since 1988. It has a distinctive dark stripe down its back on and otherwise grey body. It is found in China and Mongolia, and lives in burrows beneath desert shrubs.
The elegant water shrew is a species of mammal in the subfamily Soricinae of the family Soricidae. It is the only species within the genus Nectogale. It lives in Sikkim and China.
Phacochoerus is a genus in the family Suidae, commonly known as warthogs. They are pigs who live in open and semi-open habitats, even in quite arid regions, in sub-Saharan Africa. The two species were formerly considered conspecific under the scientific name Phacochoerus aethiopicus, but today this is limited to the desert warthog, while the best-known and most widespread species, the common warthog, is Phacochoerus africanus.
Paraechinus is a genus of hedgehogs. Members are small and nocturnal. The genus contains four species from North Africa, the Middle East and South Asia:
The Lama dwarf hamster is a species of rodent in the family Cricetidae. It is found only in the mountains of western China where it inhabits grassland, shrubby marshes and steppes. Although it has a limited range, the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
