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。

Coelacanth

1938年に南アフリカ沖で再発見されるまで6,500万年間絶滅していたと考えられていた生きた化石であるシーラカンスは、2メートル、90kgに達することができます。この種は条鰭類よりも四足動物に近い古代の肉鰭類の系統に属しており、脊椎動物の進化を理解する上で科学的に非常に重要です。インド洋の深い岩礁生息地に生息し、夜行性で体内受精により完全に形成された幼魚を産みます。絶滅危惧IA類(CR)種です。
