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。

gray wolf

灰狼是分布最广的野生犬科动物，分布范围从北美横跨欧亚大陆，栖息于冻原、森林和草原等多种生境。高度社会化的动物，以由占优势的繁殖对领导的家族群体生活。作为关键捕食者，狼调节猎物种群并深刻影响生态系统结构，黄石公园的重引入项目对此有充分证明。曾遭到严重迫害，但目前许多地区的种群正在恢复。
