Colonial bentgrass

<em>Agrostis capillaris</em>, colonial bentgrass, is a perennial grass in the family Poaceae with an extensive native range across Europe and naturalised populations in North America, South America, and Oceania, including Australia and New Zealand. This species is highly adaptable, colonising tropical and subtropical moist broadleaf forests, temperate grasslands, disturbed soils, roadsides, and cultivated landscapes within the Neotropical realm. It is assessed as Least Concern by the IUCN. Colonial bentgrass is a fine-leaved, low-growing species often used in lawn and sports turf applications due to its tolerance for close mowing and its capacity to form dense, even swards. Its panicle inflorescences bear numerous small spikelets on delicate, hair-like branches, giving the species a feathery appearance when in flower. In its naturalised range, <em>Agrostis capillaris</em> can become invasive, competing with native grass species in acid grasslands and open heathlands. The species tolerates acidic and nutrient-poor soils, attributes that contribute to its widespread persistence in degraded landscapes. Biological traits of this species remain poorly documented in the scientific literature.

Common Hippopotamus, Hippopotamus, Large Hippo

非洲最危险的大型哺乳动物，河马（Hippopotamus amphibius）体重可达3200千克，栖居于撒哈拉以南非洲的河流、湖泊和湿地。半水生生活方式使其每天最多在水中浸泡16小时以降温，夜间则在陆地上觅食草料。尽管外表看似温顺，河马极具攻击性且领地意识强烈，每年造成数百人伤亡。由于栖息地丧失和象牙非法猎杀，该物种被列为易危。
