Dozing Polar Bear, Canada, 1996
Photograph by Flip Nicklin
"Polar bears are masters at conserving energy. During their eight-month fast breeding females can lose as much as 45 percent of their weight. So heat retention is important, to avoid spending too much energy to keep warm."
(Text from "Polar Bears," January 1998, National Geographic magazine)

打瞌睡的北极熊（加拿大，1996）
摄影者：Flip Nicklin
北极熊可谓是保存体力的大师。在他们只有八个月的捕食时间里（如果天气太热，导致海面的冰太少，捕猎海豹将变得几乎不可能），雌北极熊可以失掉接近45%的体重。因此，热量的保持就变得很重要，只有这样才可以防止热量的扩散而保持体温。
