koala

澳大利亚东部和东南部的标志性有袋类动物，体重最大可达15千克，为了节省低热量桉树叶食物所提供的能量，每天最多睡眠22小时。高度特化，能够处理会致大多数其他哺乳动物死亡的有毒桉树成分，拥有专门适应解毒功能的肠道微生物群。因衣原体病、栖息地开发和气候变化导致种群锐减，2022年被列为濒危物种。

Monarch

作为世界上最令人叹为观止的迁徙昆虫之一，帝王蝶（Danaus plexippus）在北美北部繁殖地和墨西哥山地森林越冬地之间进行多代往返迁徙，距离长达 4,800 千米。鲜艳的橙黑翅膀警告捕食者：其毒性来自幼虫期取食的乳草。由于繁殖地丧失、农药和气候变化，越冬种群自 1990 年代以来已减少 80% 以上，被列为濒危物种。
