灰頦隱蜂鳥

灰颏隐蜂鸟是一种栖息于从哥伦比亚到玻利维亚安第斯干燥和湿润森林中的小型隐蜂鸟，具有褐色背部、灰色颏部和带白色尖端中央尾羽的淡黄褐色下体——与许多蜂鸟相比色调较为朴素。栖息于海拔300至1,600米的森林内部和灌木林缘，沿系统性的捕食路线拜访开花植物。雄鸟在求偶场聚集，通过持续鸣叫吸引雌鸟。

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。
