brown-throated three-toed sloth

ノドブトウミオサミオは世界で最も動きの遅い哺乳類のひとつで、中南米の熱帯雨林の樹冠に逆さまにぶら下がり、平均時速0.24kmで移動します。低い代謝率は、栄養価の乏しい葉を主食とする適応です。毛皮に生育する藻類がカモフラージュとなり、抗菌性をもつ共生菌を宿すこともあります。蛾、甲虫、菌類がナマケモノの毛皮の中に小さな生態系を形成しています。

gray wolf

最も広い分布域を持つ野生のイヌ科動物であるハイイロオオカミは、北アメリカからユーラシアにかけてのツンドラ、森林、草原などの多様な生息地に分布します。優位な繁殖ペアに率いられた家族単位の群れで生活する高度に社会的な動物です。キーストーン捕食者として獲物個体群を調整し、生態系の構造を根本的に形成することは、イエローストーンでの再導入により実証されています。かつて激しく迫害されましたが、多くの地域で個体群は回復しつつあります。
