Common Hippopotamus, Hippopotamus, Large Hippo

アフリカで最も危険な大型哺乳類であるカバ（Hippopotamus amphibius）は最大3,200kgに達し、サハラ以南アフリカの河川、湖、湿地に生息する。半水生で、体温を保つために1日最大16時間水中に沈んでいることがあり、夜間に陸上で草を食む。穏やかに見えるが非常に攻撃的で縄張り意識が強く、毎年数百人の死亡原因となっている。象牙の密猟と生息地の消失により個体数が脅かされており、危急種に指定されている。

Common Sun Beetle

<em>Amara aenea</em>, the common sun beetle, is a carabid ground beetle in the family Carabidae, order Coleoptera. It is broadly distributed across Europe and has been introduced to North America, typically inhabiting open, sunny habitats such as arable fields, grasslands, sandy heathlands, and disturbed ground with sparse vegetation. Adults are omnivorous, feeding on seeds, small invertebrates, and plant material, and are considered important predators of weed seeds in agricultural systems. <em>Amara aenea</em> is surface-active during warm, dry conditions, typically exhibiting peak activity in late spring and summer. Like many carabid beetles, it is nocturnal and shelters under stones and debris during the day. Larvae develop in the soil, where they also feed on organic matter and small invertebrates. Biological traits including precise adult lifespan, body length measurements, and detailed prey preferences remain poorly documented at the species level. The species is assessed as Least Concern by the IUCN, reflecting its wide distribution, high adaptability to disturbed environments, and no significant known threats to global population status.
