The polar bear's scientific name means "sea bear" because it's the only bear that has a body made for living in water. The heaviest bears ever weighed have been polar bears. They usually roam the ice alone but sometimes hang out in groups, especially babies with their mothers.

·You would see me most often in the Arctic Circle. But I also live in the cold, northern-most parts of North America, Europe and Asia.
·I usually live on sea ice and am one of the few members of my family able to spend long amounts of time in water.
·I spend a lot of time roaming but may settle down here and there. But my fur and a thick layer of blubber make it so I don't need a real house.
·I am very large with a huge, furry body. My feet are designed for walking on ice and have five sharp claws made for holding onto food. My stiff hair and fur help me swim well.
·I am almost all white, although my fur may turn yellow in summer.
·I am one of the world's largest land predators. I'm also the biggest member of my family.
·I can weigh more than 1,500 pounds (about 680 kilograms) but usually only get as large as 800 pounds (about 360 kilograms).
·I normally eat seals but also can dine on walruses, mussels or even berries and seaweed.
·Because I live in very cold places, few people bother me. I sometimes have problems with human hunters and oil drilling where I live. But I normally just ignore people.
·I'm very smart and am a great hunter and problem solver. I'm also an awesome swimmer and diver and have excellent underwater vision.

北极熊——地图上涂蓝色的地方是我的家

有趣的常识:

北极熊的学名叫“海洋熊”,因为它是唯一身体能适应水中生活的熊类。它是目前最重的熊。他们通常独自在冰上漫步,但是有时也会结群,特别是当熊宝宝跟熊妈妈在一起的时候。

·你会看到我经常出没于北极圈,但是我也住在北美、欧洲和亚洲寒冷的北部的大部分地区。
·我通常生活在海洋的冰上,而且我和我的家人一样能在水中呆很长时间。
·大部分时间我都在漫步,但是也可能在这儿或那儿安顿下来。但是我的皮毛和厚厚的脂肪层使得我可以这样,所以我并不需要一座真正的房子。
? 我有一个巨大的长着毛皮的身躯。我的脚专门适合在冰上行走,五个尖尖的爪子用来抓住食物,硬硬的头发和皮毛有利于我很好的游泳。
·我几乎纯白色,但在夏天,我的皮毛可能会变黄。
·我是世界上最大的陆生食肉动物之一,我也是家族中个头最大的成员。
·我体重能超过1500多磅(约680公斤),但通常我也就长到800磅(约360公斤)。
·我通常吃海豹,但也能吃海象,蚌类,甚至是浆果和海藻。
