鯨鯊

鲸鲨（Rhincodon typus）是世界上最大的鱼类，体长可超过12米、体重逾20吨，广泛分布于全球热带及温暖温带海洋。尽管体型巨大，它们却是无害的滤食性动物，以浮游生物、鱼卵和小鱼为食，通过张口游动来过滤水中的猎物。它们随浮游生物爆发进行大规模的季节性洄游。受捕捞、船只碰撞及活体鱼翅贸易影响，过去75年间种群数量减少约50%，被列为濒危物种。

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。
