Common Seal

分布最广的鳍足类动物港海豹（Phoca vitulina）栖居于北大西洋和北太平洋温带及亚北极沿海水域。成体体重可达130千克，在海中捕食鱼类、鱿鱼和甲壳动物，并在沙滩或礁岩上休息，两者时间大致相当。大而富有表情的眼睛适应于弱光下的水下视觉。港海豹是虎鲸、鲨鱼和北极熊的重要食物来源。

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。
