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。

緋紅麥鷍

绯红金刚鹦鹉(Ara macao)是美洲色彩最为绚丽的鸟类之一，拥有鲜艳的红、黄、蓝羽毛，翼展可达1米。分布于墨西哥至玻利维亚的湿润低地森林，智力高超，寿命可达75年，并终生保持配对关系。它们会长途跋涉前往富含矿物质的土壤地点，通过摄入土壤来中和种子中的毒素。被列为无危，但因栖息地丧失和宠物贸易而在局部地区受到威胁。
