Epaulard

イルカ科で最大の種であるシャチ（Orcinus orca）は体長最大9メートル、体重6トンに達し、北極から南極まですべての海洋に生息しています。独特の方言、狩猟戦略、集団間で異なる文化的伝統を持つ母系ポッドで生活する頂点捕食者です。一部の集団は魚類を、他の集団は海洋哺乳類を専門に捕食します。天敵はなく、シャチは生息するすべての海洋食物連鎖の頂点に位置します。

Ochrolechia pallescensは、Ochrolechiaceae科に属する殻状地衣類で、絶滅危惧(EN)と評価されている。古い木の樹皮に生育し、長い生態学的連続性を持つ原生林の指標種とされている。絶滅危惧の状況は、生息域全体での老熟木と巨木の消失による深刻な衰退を反映している。
