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。

Coelacanth

腔棘鱼在1938年于南非附近海域重新发现之前，被认为已灭绝了6500万年，这种'活化石'可长达2米、重达90千克。它属于比辐鳍鱼类更接近四足动物的古老肉鳍鱼类谱系，对理解脊椎动物进化具有极高的科学价值。栖息于印度洋深水岩礁生境，夜行性，通过体内受精产下完全发育的幼鱼。极危（CR）物种。
