brown bear

棕熊是世界上分布最广泛的熊类物种，从北美和欧洲横跨俄罗斯至日本，占据森林、冻原和高山草甸。阿拉斯加沿海种群的成年个体体重可达700公斤。棕熊是杂食性动物，以浆果、根茎、鱼类和腐肉为食，是跨景观分配养分的关键物种。大多数种群稳定，但部分亚种受到威胁。

帝企鹅

帝企鹅是世界上体型最大的企鹅，身高可达1.2米，体重达45千克，栖息于南极大陆极端恶劣的环境中。它们在隆冬的黑暗中、零下60°C以下的严寒里繁殖，雄鸟将唯一的蛋置于脚背上，藏于育卵囊下孵化长达65天，而雌鸟则在此期间出海觅食。数千只帝企鹅组成的群体通过循环交换位置、使个体轮流经过温暖的核心区域这一抱团取暖行为，堪称合作生存的典范。
