白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

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。
