藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

brown-throated three-toed sloth

棕喉三趾树懒是世界上行动最缓慢的哺乳动物之一，倒挂于中南美洲热带雨林的林冠层，平均时速仅0.24公里。其低代谢率是对营养贫乏的叶片食性的关键适应。毛皮中生长的藻类提供伪装，并可能携带具有抗菌特性的共生真菌。蛾、甲虫和真菌在树懒毛皮中形成一个微型生态系统。
