Buck (short for Buckminster) was a weasel that makes an appearance in Ice Age: Dawn of the Dinosaurs.

Originally, the name "weasel" was applied to one species of the genus, the European form of the Least Weasel (Mustela nivalis). Early literary references to weasels, for example their common appearances in fables, refer to this species rather than to the genus as a whole, reflecting what is still the common usage in the United Kingdom. In technical discourse, however, as in American usage, the term "weasel" can refer to any member of the genus, or to the genus as a whole.

這是《冰河世紀》第三部中的新角色，一只叫做Buck的鼬鼠，這位瘋瘋癲癲的獨眼龍老兄是不是讓你想起了《獅子王》中經(jīng)典的貓釉丁滿咧？

鼬鼠有一種體形很小的黃鼠狼，它廣泛分布于亞北極地區(qū)的叢林中，有時也穿越叢林的邊緣進入北極苔原，但嚴格說來，它們算不上是北極居民。常年生活在北極草原上的最小的食肉動物是鼬鼠，或稱之為貂，它們才是真正的北極居民。
