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。

葵花鳳頭鸚鵡

葵花凤头鹦鹉（Cacatua galerita）是最大、最具代表性的凤头鹦鹉之一，栖息于澳大利亚东部、新几内亚和摩鹿加群岛的森林和疏林地带，已被引入新西兰。它们高度聪明、寿命长（圈养时最长可达70年）、高度群居，以嘈杂著称，叫声在1公里以外均可听到。它们在城市地区剥树皮、啃木材、损坏农作物，成为害鸟，展示出对人类改造环境的惊人适应能力。
