African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

Chaetoceros diversusは、珪藻類の中で最も種が多い属の一つに属する海産浮遊珪藻類だ。水柱内での沈降速度を低下させる長い針状の剛毛（糸状突起）を持つ珪酸質細胞の鎖状群体を形成する。この珪藻は世界中の沿岸および外洋環境に生息し、海洋一次生産と地球炭素循環に重要な役割を果たす。
