blue whale

地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

Monarch

世界で最も驚くべき渡り昆虫の一つで、オオカバマダラ（Danaus plexippus）は北アメリカ北部の繁殖地とメキシコの山岳森林の越冬地との間を最大 4,800 km の多世代往復移動を行います。鮮やかなオレンジと黒の翅は幼虫時に食べたトウワタから得た毒性を捕食者に警告します。1990年代以降、繁殖地の消失、農薬、気候変動により越冬個体群が 80%以上減少し、絶滅危惧種に指定されています。
