ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

Hira-shumokuzame

最大のシュモクザメ種であるオオシュモクザメは最大6メートルに達し、世界中の熱帯および亜熱帯の沿岸海域に生息します。T字型の特徴的な頭部（セファロフォイル）は電気受容のための感覚表面積を著しく増大させ、砂の中に潜むアカエイを卓越した精度で探知することを可能にしています。アカエイは好物の餌です。高価値のヒレと混獲死亡により個体群が劇的に減少し、絶滅危惧IA類に分類されています。
