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。

Alexandrium minutumは麻痺性貝毒の原因となるサキシトキシンを産生することで知られる小型の装甲海洋渦鞭毛藻である。世界中の温帯から温暖な沿岸・河口域に生息する。有害藻類ブルームを形成し、濾過摂食性二枚貝の体内に毒素が蓄積する原因となる。
