elk

アカシカとも呼ばれるエルク（Cervus elaphus）は、枝角を持つ雄が最大240kgに達するシカ科最大種の一つです。ヨーロッパ、アジア、北アメリカの温帯林や草原に分布し、歴史的には個体群が別の亜種として区別されていました。雄は毎年枝角を落として再生させ、秋の繁殖期には激しい鳴き声競争を繰り広げます。分布域全体にわたって重要なジビエ動物であり、保全対象種です。

jaguar

アメリカ大陸最大のネコ科動物で、体重は最大100kgに達し、がっしりとした筋肉質の体型と特有のロゼット模様の毛皮を持つ。メキシコから南アメリカにかけて分布し、アマゾンやパンタナルが主要生息地となる。優れた水泳能力を持つ頂点捕食者であり、獲物個体数の調節に重要な役割を担う。森林破壊により生息域が縮小し、準絶滅危惧に分類されている。
