Fly Agaric

毒蝇鹅膏菌（Amanita muscaria）是地球上最具标志性和辨识度的真菌，在北半球寒带森林中展示出点缀白色鳞片的鲜红色菌盖。尽管外观如童话般，它含有包括蝇蕈醇和鹅膏氨酸在内的强效致幻化合物，具有中度毒性。它与桦树、松树和云杉形成关键的菌根共生关系，交换矿物质营养和碳，在寒带森林养分循环中发挥不可或缺的作用。

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。
