紫頦鬆腿蜂鳥

发光腿绒蜂鸟是一种色彩绚丽的腿绒蜂鸟，分布于从哥伦比亚到厄瓜多尔南部的北安第斯山脉，在明亮光线下展示出几乎发光般的鲜艳虹彩绿色羽毛，这正是该物种描述性俗名的灵感来源。栖息于海拔1,800至3,500米的湿润山地林。雄鸟具有特征性的白色腿绒和闪耀的紫蓝色尾羽。是安第斯高山开花植物的重要传粉者，被列为无危。

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。
