黑脚毛腿蜂鸟

黑腿绒腿蜂鸟（Eriocnemis derbyi）因雄鸟独特的黑色大腿与白色腿部羽毛簇形成强烈对比而得名，栖息于厄瓜多尔和哥伦比亚海拔1,500至3,500米的湿润山地森林和林缘。雄鸟展示翠绿色羽毛和蓝紫色尾羽。由于安第斯云雾林遭农业开垦，种群数量下降，被列为近危（NT）物种。

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。
