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。

紅領綠鸚鵡

亚历山大鹦鹉（Psittacula krameri）是世界上分布最广、最具入侵性的鹦鹉之一，原产于撒哈拉以南非洲和南亚，但从逃逸笼鸟发展出来，已在包括欧洲、北美、日本和澳大利亚在内的35个以上国家建立了大型野化种群。雄鸟具有独特的粉红和黑色颈环。适应力强、繁殖力高，在伦敦、阿姆斯特丹、布鲁塞尔等城市中野化种群急剧增加，形成庞大的栖息群落，并与本土洞巢鸟类展开竞争。
