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。

Coelacanth

1938年に南アフリカ沖で再発見されるまで6,500万年間絶滅していたと考えられていた生きた化石であるシーラカンスは、2メートル、90kgに達することができます。この種は条鰭類よりも四足動物に近い古代の肉鰭類の系統に属しており、脊椎動物の進化を理解する上で科学的に非常に重要です。インド洋の深い岩礁生息地に生息し、夜行性で体内受精により完全に形成された幼魚を産みます。絶滅危惧IA類（CR）種です。
