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。

large flying fox

世界最大のコウモリ種で、翼開長は最大1.5メートルに達し、東南アジアからフィリピン・インドネシアにかけての熱帯林に生息する。その名に反して果実と花蜜のみを食べ、熱帯林の樹木にとって不可欠な花粉媒介者・種子散布者となっている。数千頭もの巨大なコロニーでねぐらを作る。食用のための狩猟と生息地破壊により絶滅危惧種に指定されている。
