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。

長尾蜂鳥

长尾精灵蜂鸟(Aglaiocercus kingii)是装饰最为华丽的蜂鸟之一。雄性具有虹彩绿色羽毛和极度延长的带状外侧尾羽,可达22厘米,超过体长的三倍。分布于哥伦比亚和委内瑞拉安第斯云雾林海拔1400至2800米处。雄性会进行精心的展示飞行以吸引雌性。其华美的尾羽是雌性偏好驱动性选择的经典案例。
