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。

灰蓝食籽雀

一种栖息于从尼加拉瓜经中美洲至南美洲太平洋坡延伸到玻利维亚的开阔草原、热带稀树草原和林缘的小型板岩蓝色食籽鸟，雄鸟全身羽毛呈均匀深板岩灰色，具有淡色喙。小群觅食草类种子，常见于林缘附近高草地中。与许多Sporophila食籽雀一样，受到笼鸟贸易捕获和牧场转换造成的栖息地丧失的影响。
