林鸱

灰潜鸟（Nyctibius griseus）是栖居于从墨西哥到阿根廷的中美洲和南美洲热带森林的夜行性鸟类，白天静止不动地栖息在折断的树桩或树枝上，眼睛微张，保护色完美到几乎与树皮融为一体，捕食者难以发现。入夜后，它们从暴露的栖枝上张开巨大的嘴捕食大型昆虫。其哀婉、令人毛骨悚然的鸣叫声在热带雨林的夜晚回荡不绝。

虎鯨

作为海豚科体型最大的成员，虎鲸（Orcinus orca）体长可达9米，体重6吨，分布于从北极到南极的所有海洋。以母系群体生活的顶级捕食者，不同种群具有独特的方言、狩猎策略和文化传统。一些种群专门捕食鱼类，另一些则捕食海洋哺乳动物。没有天敌，虎鲸位于其所栖居的每条海洋食物链的顶端。
