クリスマスアオバズク

The Christmas Island boobook (Ninox natalis) is a small owl in the family Strigidae, endemic to Christmas Island, an Australian territory located in the Indian Ocean approximately 360 kilometers south of Java, Indonesia. It is one of a suite of highly distinctive endemic vertebrates found only on Christmas Island, reflecting the island's long isolation from mainland Australia and Southeast Asia. The species belongs to the boobook owl group, which is distributed across Australasia and the broader Indo-Pacific region. As a small predatory owl, the Christmas Island boobook feeds primarily on insects and small vertebrates, hunting at night in the dense tropical forest that covers much of the island. The remaining rainforest on Christmas Island provides critical habitat for this species. Conservation concerns for the Christmas Island boobook include invasive species, particularly the invasive yellow crazy ant (Anoplolepis gracilipes), which has devastated seabird colonies and dramatically altered forest structure and invertebrate communities on the island. Habitat degradation from phosphate mining activities has also affected parts of the island. The species has a small total population restricted entirely to Christmas Island and warrants ongoing monitoring and targeted conservation management.

Lion

アフリカ最大の野生ネコ科動物で最大250kgに達し、サハラ以南のサバンナや草原に生息する唯一の社会性ネコ科動物です。雄は象徴的なたてがみで識別されます。頂点捕食者として草食動物の個体群を調節し、生態系のバランスを維持します。生息地の喪失と人間との軋轢により危急種に分類されています。
