cloud grass

Cloud grass refers to ornamental and native grasses in the genus Agrostis (family Poaceae), particularly Agrostis nebulosa, a delicate annual grass native to the Iberian Peninsula and northwestern Africa that produces large, airy, cloud-like panicles of minute spikelets on extremely fine, hair-like branches. The panicle's ethereal, misty appearance in mass gives the plant its evocative common name. It grows in dry, sandy soils and disturbed ground, completing its life cycle quickly in spring before summer drought conditions. Agrostis nebulosa is widely cultivated as an ornamental grass for cut flower arrangements and dried flower compositions, where its delicate panicles add texture and movement to floral displays. The genus Agrostis, bent grasses, encompasses dozens of perennial and annual species distributed across cool temperate and alpine zones worldwide, including the fine-leaved bent grasses used in golf greens and lawns for their dense, low-growing turf. Many Agrostis species are characteristic of acidic, nutrient-poor soils in heathlands, moorlands, and montane grasslands across Europe and North America.

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。
