common warthog

<em>Phacochoerus africanus</em>, commonly known as the common warthog, is a wild member of the family Suidae (pigs) widely distributed across sub-Saharan Africa, inhabiting a broad swath of savanna, grassland, and open woodland habitats from Senegal and Ethiopia south to South Africa and Namibia. This species is highly adaptable and typically occupies open or lightly wooded landscapes with short grass and access to wallowing sites and water. <em>Phacochoerus africanus</em> is immediately recognizable by the prominent facial "warts" — enlarged dermal structures on the snout that are larger in males — and the impressive upward-curving tusks formed from elongated canine teeth used in defense and social competition. Warthogs are omnivorous but primarily herbivorous, feeding on grasses, roots, bulbs, bark, and fallen fruit, and are notable for the distinctive posture of kneeling on their front "wrist" pads while rooting for food. They use burrows excavated by other animals, particularly aardvarks, for shelter and rearing young. Natural predators include lions, leopards, cheetahs, wild dogs, and crocodiles. The species is currently assessed as Least Concern by the IUCN, with populations stable and abundant across protected areas. Population trend data is stable. Biological traits including average lifespan of up to 15 years, body lengths of 90 to 150 centimeters, and weights of 45 to 150 kilograms are documented across the literature.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
