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。

紅額鸚鵡

红额鹦鹉（Cyanoramphus novaezelandiae）是一种具有鲜艳红色头顶和脸颊斑块的小型亮绿色鹦鹉，为新西兰特有种，栖息于从海平面到高山带的森林中。适应性极强，觅食种子、花朵、果实和昆虫。由于引入的捕食者（鼠类、白鼬、猫）威胁，在本土已濒危，但在无哺乳动物的近海岛屿上维持着健康种群。保育迁移和捕食者控制项目支持本土种群恢复。
