Ratlike Hamster
''Cricetulus'' is a genus of rodent in the family Cricetidae ( voles and hamsters); it has seven member species that inhabit arid or semi-arid regions in Eurasia. They tend to be more ratlike in appearance than typical hamsters, hence the common name ''ratlike hamster''. Many of the species are considered dwarf hamsters. However, members of the genera ''Allocricetulus'', ''Tscherskia'', and ''Cansumys'' are often called ''ratlike hamsters'', and so are considered to be members of the genus ''Cricetulus'' by many authorities.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Phodopus
''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 (roughly ) relative to other hamsters. Like other hamsters, members of ''Phodopus'' have a round body shape, short tails and cheek pouches in which they can store food. They all live in dry conditions with extreme temperatures. They inhabit the forests, steppes and semi-deserts of Mongolia, Siberia, China and Kazakhstan. Fossils of ''Phodopus'' have been found in Pleistocene ...

Sokolov's Dwarf Hamster
Sokolov's dwarf hamster (''Cricetulus sokolovi'') 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. Taxonomy ''Cricetulus sokolovi'' was previously attributed to ''C. barabensis obscurus'', but was elevated to species status in 1988 due to differences in its chromosomes and fur. It is named after Russian zoologist Vladimir E. Sokolov. Description It’s fur is grey with a brown-yellow hue. A dark stripe runs from the back of a specimen's neck to the base of its tail. This stripe is seen more easily in younger animals and fades with age. Its feet are white and its toes curl upwards. It’s ears are the same color as its fur, with a dark grey spot in the inside middle. It has a head-body-length of b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chinese Striped Hamster
The Chinese striped hamster (''Cricetulus barabensis''), also known as the striped dwarf hamster, is a species of hamster. It is distributed across Northern Asia, from southern Siberia through Mongolia and northeastern China to northern North Korea. An adult Chinese striped hamster weighs , and has a body length of with a tail of . It is smaller and has a much shorter tail than the greater long-tailed hamster, ''Tscherskia triton'', which inhabits much of the same range. Taxonomy The Chinese striped hamster was first described in 1773 as ''Cricetulus barabensis'' by the German zoologist Peter Simon Pallas. There is quite some confusion over the Latin name of the Chinese striped hamster and the closely related Chinese hamster. Some people consider the Chinese hamster (''Cricetulus griseus'') and the Chinese striped hamster (''Cricetulus barabensis'') different species, whereas others classify them as identical, the Chinese striped hamster as a subspecies of the Chinese hamste ...

Chinese Hamster
The Chinese hamster (''Cricetulus griseus'' or ''Cricetulus barabensis griseus'') 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.

Males have a fairly large scrotum relative to their body size. Their body proportions, compared to other hamster species – most of which tend to be compact – appear "long and thin" and they have (for a hamster) a relatively long tail. They live two to three years on average. The wild colour is brown with a black stripe down the spine, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
