アスペロコッカス・エンシフォルミス(Asperococcus ensiformis)は北大西洋・地中海沿岸の岩礁基質に付着する管状〜扁平な茶藻類で、細長い袋状〜剣形の葉状体を形成する。潮間帯から浅い潮下帯の波浪暴露域の岩石・大型藻類に着生する光合成植物である。コンブ目に近縁な褐藻類として、沿岸生態系の一次生産者として機能している。
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。
