Atlantic Bluefin Tuna

大西洋蓝鳍金枪鱼（Thunnus thynnus）是世界上体型最大、游速最快、经济价值最高的鱼类之一，最大个体体重可超过600千克。该物种保护状态为濒危（EN），由于过度捕捞，其野生种群数量急剧下降，单条优质个体在日本拍卖市场上的成交价曾超过300万美元。

藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。
