倉鼠是倉鼠亞科動物的總稱。共七屬十八種,主要分佈于亞洲,少數分佈于歐洲,其中中國有三屬八種。除分佈在中亞的小倉鼠外,其他種類的倉鼠兩頰皆有頰囊,從臼齒側延伸到肩部。可以用來臨時儲存或搬運食物回洞儲藏,故名倉鼠,又稱腮鼠、搬倉鼠。
倉鼠有一對不斷生長的門牙,三對臼齒,齒型為:1 0 0 3,成交錯排列的三稜體。臼齒具齒根,或不具齒根而終生能生長。
該科各種類動物基本都屬中小型鼠類。體長在5~28厘米之間,體重在30~1000克。體型短粗。尾短,一般不超過身長的一半,部分品種不超過後腿長度的一半,甚至基本看不到。主要食物為植物種子,喜食堅果,亦食植物嫩莖或葉,偶爾也吃小蟲。多數不冬眠,冬天靠儲存食物生活。少數品種在天氣寒冷情況下會進入不太活躍的准冬眠狀態。
倉鼠主要在夜間活動,視力差,只能模糊辨形,顏色只能分辨黑白。毛色繁雜。春末後繁殖,年2~3胎,每胎5-12隻。平均壽命2-3年。
倉鼠部分品種因為和人親近,已成為近年流行的寵物,如黃金倉鼠、加卡利亞倉鼠、坎貝爾倉鼠、羅伯羅夫倉鼠等。
Hamsters are rodents belonging to the subfamily Cricetinae. The subfamily contains about 18 species, classified in six or seven genera.
The name hamster is derived from the German word Hamster, itself from earlier OHG hamustro, from ORuss choměstorǔ, which is either a blend of the root of Russ khomiak "hamster" and a Baltic word (cf. Lith staras "hamster")[1] or of Iranian origin (cf. Av hamaēstar "oppressor")[2].
Behavior can vary depending on their environment, genetics, and interaction with people. Because they are easy to breed in captivity, hamsters are often used as lab animals in more economically developed countries. Hamsters have also become established as popular small pets.
Hamsters are crepuscular. In the wild, they burrow underground in the daylight to avoid being caught by predators. Contrary to popular belief they are a nocturnal animal. Their diet contains a variety of foods, including dried food, berries, nuts, fresh fruits and vegetables. In the wild they will eat any wheat, nuts and small bits of fruit and vegetables that they might find lying around on the ground, and will occasionally eat small insects such as small crickets or mealworms. They have elongated fur-lined pouches on both sides of their heads which extend to their shoulders, which they stuff full of food to be brought back to the colony or to be eaten later.
