Hohojirozame

地球上で最大の捕食性魚類であるホホジロザメは、全世界の主要な大洋の冷涼な沿岸・外洋域に生息し、体長6メートル、体重2,000キログラムに達することがあります。海洋哺乳類、大型魚類、海鳥を主な獲物として下方からの待ち伏せ攻撃を行う最上位捕食者です。その恐ろしい評判にもかかわらず、人間への非挑発的な攻撃は極めてまれです。フカヒレ採取、混獲、目的的漁獲によって個体数が減少しており、多くの地域で法的保護を受けているにもかかわらず危急(VU)に分類されています。

Ardilla Gris Oriental

ヒガシハイリス(Sciurus carolinensis)は北米東部原産の中型樹上性げっ歯類で、ヨーロッパをはじめ世界各地に移入された外来種である。IUCNレッドリストでは軽度懸念(LC)に分類されており、都市公園や郊外の森林環境への適応力が高く、堅果の埋蔵行動が植物の種子散布に重要な役割を果たしている。英国ではニホンリスを食物競争で駆逐しており、侵略的外来種としても問題視されている。
