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。

長嘴星喉蜂鳥

长嘴星喉蜂鸟(Heliomaster longirostris)是一种大型独特的蜂鸟,具有异常细长而笔直的喙。雄性喉部羽毛呈虹彩绿色,眼后有醒目的白色斑块。分布从墨西哥经中美洲延伸至安第斯山脉以东的热带南美,海拔可达1500米。栖息于林缘、空地和花园,习惯停落于树顶暴露的枝条上,这与通常悬停觅食的蜂鸟有所不同。
