Canadian beaver

北美最大的啮齿动物加拿大河狸体重可达32公斤，是栖息于加拿大和美国北部河流、湖泊和湿地的杰出生态系统工程师。通过伐木和建造可达数百米的水坝形成水塘，为数百种物种提供生境。其巢穴和运河改变了整个流域。曾因毛皮贸易被猎杀至濒临灭绝，但种群已大幅恢复。

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。
