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 (some sources state the hamster is not kept widely as a pet〔〔 while others simply say it cannot be kept as a pet due to its aggressive nature.〔) 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 Cricetidae family.〔 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,〔 living in scrublands, sand dunes, desert steppes and farmlands.〔 The land where the Turkish hamster lives is extremely dry and open, with fairly little vegetation aside from grasses.〔 Turkish hamsters usually live between 1,000 and 2,200 meters above sea level.〔 This hamster burrows in the ground for shelter,〔 and its burrows can be 20 inches to 6 feet below the ground surface.〔 These burrows are complex, consisting of several tunnels leading to separate cells for nesting, food, and waste.〔 Turkish hamster burrows are well-enough equipped for the hamsters to hibernate for four to 10 months (though sources do differ on this point),〔〔 sometimes sleeping for 30 days at a time,〔 though usually waking weekly for a day or two of activity.〔〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Turkish hamster」の詳細全文を読む スポンサード リンク
