Common Seal

最も広く分布する鰭脚類であるゴマフアザラシの近縁種・ゼニガタアザラシ(Phoca vitulina)は、北大西洋と北太平洋の温帯・亜北極沿岸に生息する。成体は最大130kgに達し、海での魚・イカ・甲殻類の捕食と海岸や岩場での休息にほぼ同じ時間を費やす。大きく表情豊かな目は低照度での水中視覚に適応している。シャチ・サメ・ホッキョクグマにとって重要な食料源である。

Usnea cornutaはParmeliaceae科の果状地衣類で、準絶滅危惧(NT)と評価されています。樹木の枝や小枝に垂れ下がる茂み状の葉状体を形成し、主に湿潤な森林環境に生息します。すべてのUsnea属の種と同様に大気汚染、特に二酸化硫黄に対して非常に敏感で、大気質の有用な生物指標として利用されます。
