elk

アカシカとも呼ばれるエルク（Cervus elaphus）は、枝角を持つ雄が最大240kgに達するシカ科最大種の一つです。ヨーロッパ、アジア、北アメリカの温帯林や草原に分布し、歴史的には個体群が別の亜種として区別されていました。雄は毎年枝角を落として再生させ、秋の繁殖期には激しい鳴き声競争を繰り広げます。分布域全体にわたって重要なジビエ動物であり、保全対象種です。

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。
