common bottlenose dolphin

最も研究され、最も知られているイルカ種であるバンドウイルカは、沿岸の浅瀬から外洋まで世界中の温暖な海域と温帯海域に生息します。体に対して大きな脳を持つ高度に知性的なこの種は、自己認識、複雑なコミュニケーション、社会的学習を示します。流動的な分裂融合社会で生活し、魚を追い込むために協力します。海洋生態系の健全性の重要な指標種です。

コウテイペンギン

世界最大のペンギンであるコウテイペンギン（Aptenodytes forsteri）は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
