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。

紫背刺嘴蜂鳥

紫背刺嘴蜂鸟（Ramphomicron microrhynchum）是雄鸟背部和腰部具闪亮紫色羽毛的小型高山蜂鸟，其独特的短嘴适应于短管状花朵。分布于委内瑞拉、哥伦比亚、厄瓜多尔和秘鲁海拔2500至4500米的帕拉莫草地和云雾林边缘。尽管体型微小，却会积极捍卫花丛领地，是适应高海拔寒冷环境最出色的蜂鸟之一。
