白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

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。
