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。

Fly Agaric

ベニテングタケ（Amanita muscaria）は地球上で最も象徴的で広く知られる菌類であり、北半球の北方林全域に白いいぼのある鮮やかな赤い傘を広げる。童話のような外見とは裏腹に、ムシモールやイボテン酸などの強力な向精神性化合物を含み、中程度の毒性がある。シラカバ、マツ、トウヒと重要な外生菌根共生関係を形成し、無機栄養素と炭素を交換することで北方林の栄養循環に不可欠な役割を担っている。
