北極的"居民"是如何過冬的?
Arctic Hare
Shortened ears and thick, white fur are among the physical traits that arctic hares have adapted to survive in the harsh, frozen tundra.
北極兔
爲了適應北極的凍土和艱苦的生活環境，北極兔進化出了短耳朵和厚厚的雪白色皮毛。
Arctic Fox
The lush white coat of the arctic fox provides both warmth and camouflage in winter.
北極狐華麗的雪白大衣爲它抵禦了嚴寒，同時還提供了躲避天敵的僞裝。
Baby Harp Seal
A baby harp seal rests on the Arctic ice. Its mother can distinguish it from hundreds of others by scent alone.
格陵蘭海豹寶寶們正在北極冰蓋上休息。它們的媽媽可是火眼金睛，能通過氣味從成百上千只海豹寶寶中找到自己的孩子。
Desert Cottontail Rabbit
Ubiquitous throughout North and South America, cottontail rabbits, including this desert variety, are noted for their fluffy "cotton" tail.
沙漠白尾灰兔
在北美洲和南美洲，這種白尾灰兔幾乎到處可見，包括這種以毛茸茸的尾巴而聞名的沙漠白尾灰兔。
Snowshoe Hare
The aptly named snowshoe hare has particularly large feet and a winter-white coat. In the summer though, their fur turns brown, taking up to ten weeks to change color completely.
北美野兔
北美野兔因大腳和雪白的皮毛而得名，儘管在夏天它就變成棕色了，而這需要10周時間。
Musk-Oxen
Thick, shaggy fur keeps musk-oxen warm in the harsh Arctic tundra.
麝牛
厚厚的蓬鬆長毛使得麝牛即使身處北極凍土，也不會怕冷。
小編物語：
看了這些家住北極的可愛小朋友，有沒有心生憐惜呢？隨着氣候變化，它們的家園越來越小，又沒有適宜的地方可以搬遷……所以，希望看到這裏的你可以從點滴做起，愛護身邊的一花一木，一草一樹，保護好我們共同的家園。
Siberian Tigers
Of the three remaining species of tigers, Siberian tigers are the largest. While there are only 400 to 500 left in the wild, the population is considered stable, and conservation programs are introducing captive-born tigers to the wild.
西伯利亞虎
世界僅存的三個虎種中，西伯利亞虎算是保留最多的一種了。但野生西伯利亞虎只有400到500只，數量穩定，動物保護機構正在研究如何野化人工馴養老虎的後代，讓其重返自然。
Bighorn Sheep
Bighorn sheep live in divided herds: ewes and lambs together in larger groups, rams in smaller bachelor herds. They usually only cross paths in the fall for mating.
大角羊
大角羊這種生物是分開聚居的：母羊和羔羊在一起，公羊單獨聚成一個小羣體。兩個羣體只有在秋天交配的時候纔會碰面。
King Penguins
King penguins' flippers are distinctively large, helping them dive deep in the icy ocean. On land, they waddle and toboggan across the ice—sliding on their bellies, and propelling themselves with their flippers.
國王企鵝
國王企鵝的鰭非常大，這使它們能在水中潛得更深。在陸地上，它們只能步履蹣跚，或肚子着地，用巨大的鰭滑行。
Emperor Penguins
Emperor penguins are the largest penguins, standing about 4 feet (1.2 meters) tall.
帝企鵝
帝企鵝是最大的企鵝品種，站着有約4英尺（1.2米）高。
