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。

ワシミミズク

世界最大のフクロウ種であるワシミミズク（Bubo bubo）は翼開長最大1.9メートルに達し、ヨーロッパからアジアを経て中国にかけての岩石地帯、林縁、断崖に生息します。強力な爪を持つ静かな夜行性ハンターで、ウサギ、野ウサギ、キツネ、さらには他の猛禽類も獲物にします。深みのある響き渡る鳴き声は遠くまで届きます。歴史的に迫害されてきましたが、個体群は比較的安定しています。
