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 Roller

<em>Ancylis badiana</em>, the common roller, is a small moth in the family Tortricidae, order Lepidoptera. It is distributed across northwestern Europe, with documented records from Belgium, Denmark, Norway, and Sweden, typically inhabiting woodland margins, hedgerows, scrubland, and areas where its larval host plants are abundant. The species is assessed as Least Concern on the IUCN Red List. Tortricid moths in the genus Ancylis are commonly known as "rollers" or "leafrollers" because their larvae typically roll or fold leaves of host plants to create sheltered feeding structures. <em>Ancylis badiana</em> larvae feed on the foliage of various herbaceous plants, particularly species in the pea family (Fabaceae). Adults are small moths with intricately patterned wings that provide camouflage against bark and plant material. Adult moths are primarily nocturnal and are attracted to light, while larvae are cryptic within their leaf shelters. Biological traits such as lifespan, body measurements, and detailed diet host range remain poorly documented beyond general family-level characteristics. The species typically completes one to two generations per year in temperate European climates, overwintering as pupae. It is considered a minor component of invertebrate biodiversity in European lowland habitats.
