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。

白头文鸟

白头文鸟（Lonchura maja）是一种具有独特白色头部和栗色胁部的中型群居梅花雀，分布于从泰国至菲律宾的东南亚森林、次生林和稻田。高度合群，常聚集成大群觅食草种和稻谷。白色头部与深褐色体羽形成鲜明对比，是视觉上最具特色的文鸟之一。在亚洲是深受喜爱的笼养鸟，人工饲养下繁殖较为容易。
