横斑鹦哥

横纹小鹦鹉（Bolborhynchus lineola）是新大陆鹦鹉中体型最小的种类之一，栖息于从墨西哥南部至厄瓜多尔西部的中南美洲海拔1200至3000米的湿润山地森林。其绿色底色上特有的黑色横纹羽毛提供了出色的林冠伪装。常结成小群觅食种子和浆果，尤其偏爱竹林。相较于其他鹦鹉较为安静低调，野外研究甚少，部分鸟类爱好者有饲养记录。

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。
