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。

Ceratoneis closteriumは、繊細に先細りした湾曲した細胞端を持つ細長い三日月形の海産・汽水珪藻類だ。温帯から熱帯海域にかけての沿岸海洋および河口域の浮遊環境に生息する。この光合成珪藻は植物プランクトン群集に寄与し、沿岸水域で動物プランクトンの餌となる。
