Mesocricetus
''Mesocricetus'' is a genus of Old World hamsters, including the Syrian or golden hamster, the first hamster to be introduced as a domestic pet, and still the most popular species of hamster for that purpose.

Mesocricetus Auratus
The golden hamster or Syrian hamster (''Mesocricetus auratus'') 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. Syrian hamsters are larger than many of the dwarf hamsters kept as pocket pets (up to five times larger), and weigh about the same as a sugar glider, though the wild European hamster exceeds Syrian hamsters in size. They are also used as scientific research animals throughout the world. Characteristics The size of adult animals is around long, with a lifespan of 2–3 years. Body mass is usually in th ...

Hamster
Hamsters are rodents (order Rodentia) belonging to the subfamily Cricetinae, which contains 19 species classified in seven genera.Fox, Sue. 2006. ''Hamsters''. T.F.H. Publications Inc. They have become established as popular small pets. The best-known species of hamster is the golden or Syrian hamster (''Mesocricetus auratus''), which is the type most commonly kept as pets. Other hamster species commonly kept as pets are the three species of dwarf hamster, Campbell's dwarf hamster (''Phodopus campbelli''), the winter white dwarf hamster (''Phodopus sungorus'') and the Roborovski hamster (''Phodopus roborovskii''). Hamsters are more crepuscular than nocturnal and, in the wild, remain underground during the day to avoid being caught by predators. They feed primarily on seeds, fruits, and vegetation, and will occasionally eat burrowing insects. Physically, they are stout-bodied with distinguishing features that include elongated cheek pouches extending to their shoulders, which ...

Ciscaucasian Hamster
The Ciscaucasian hamster (''Mesocricetus raddei'') is a species of rodent in the family Cricetidae. It is also known as the Georgian hamster and is found only in Georgia and Russia. Distribution and habitat This hamster occurs on the northern slopes of the Caucasus and Ciscaucasia, between Dagestan, the Don River and the Sea of Azov. It is also known from a single record in Georgia. It appears to be extending its range north and north-westwards in its plains habitats but in the mountains the population remains stable. It is found in grassy steppes and also mountain steppes at elevations from 1600 to 2300 m above sea level. It favours pasture and cultivated land and also occurs in belts of trees and rough grass between fields but not in dense woodland.''Mesocricetus radd ...

Turkish Hamster
The Turkish hamster (''Mesocricetus brandti''), also referred to as Brandt's hamster, Azerbaijani hamster, or ''avurtlak'', is a species of hamster native to Turkey, Armenia and other surrounding nations. The Turkish hamster, first catalogued in 1878, is a fairly close relative of the Syrian or golden hamster, though far less is known about it, and it is rarely kept as a pet. The population of the Turkish hamster is said to be declining in the wild, yet this hamster is often used in laboratory testing. Turkish hamsters have lifespans of about two years and are solitary, nocturnal animals, which practice hibernation. They are reported to be more aggressive than other members of the family Cricetidae. They are tan and dark, sandy brown in color. Like all hamsters, the Turkish hamster has cheek pouches that allow it to carry large amounts of food at one time. Habitat and behavior Hamsters are found in the wild throughout Europe and Asia and are considered to be extremely adaptable, ...

Brandt was born in Jüterbog and educated at a Gymnasium (school), gymnasium in Wittenberg and the Humboldt University of Berlin, University of Berlin. In 1831 he emigrated to Russia, and soon was appointed director of the Zoological Museum of the St Petersburg Academy of Sciences.
