北極狐? 正在睡覺(jué)的北極狐 我們相信你可以把這只正在打盹的北極狐擠成一個(gè)毛絨玩具，但我們不建議這樣做。這些可愛的小毛絨球可能是兇猛的獵人。事實(shí)上，北極狐是凍土帶上最多產(chǎn)的捕食者之一，捕食旅鼠、田鼠、兔子、鳥類（通常有一面是蛋）和其他穿過(guò)它們可愛路線的小動(dòng)物。但是現(xiàn)在，我們的北極狐很樂(lè)意蜷縮著尾巴，用它的身體組成一個(gè)球來(lái)保持安靜，狐貍將盡可能少的表面積暴露在冷空氣中，無(wú)論水銀柱下降到多低，都有助于保存熱量。

原文:

We're sure you could just squeeze this snoozing Arctic fox like a stuffed animal, but we wouldn't advise it. These cute little fuzzballs can be ferocious hunters. In fact, the Arctic fox is one of the most prolific predators on the tundra, preying on lemmings, voles, rabbits, birds (often with a side of eggs), and other small critters that cross their adorable path. But right now, our Arctic fox is happy to curl up with its tail and get some shuteye—by forming a ball with its body, the fox is exposing the least possible surface area to cold air, helping to conserve heat no matter how low the mercury dips.
