Common Spike-thorn

<em>Gymnosporia buxifolia</em>, commonly known as the common spike-thorn, is a spiny shrub or small tree in the family Celastraceae, native to sub-Saharan Africa. This species typically inhabits a variety of vegetation types including bushveld, riverine thickets, rocky hillsides, forest margins, and disturbed areas, demonstrating considerable ecological versatility. It is widely distributed across eastern and southern Africa, with populations recorded in countries including South Africa, Zimbabwe, Mozambique, Tanzania, and Kenya, among others in the region. Classified as Least Concern on the IUCN Red List, <em>Gymnosporia buxifolia</em> is considered stable throughout much of its range. The plant is characterised by its stout axillary thorns, small dark green leaves, and small white to cream flowers followed by three-lobed capsular fruits. It plays an ecological role as a host plant for various insects and as a food source for browsing mammals. Biological traits such as average lifespan, body dimensions, and dietary specifics remain poorly documented in the scientific literature for this plant species. The species is also used in traditional medicine across parts of its range, and its dense thorny growth makes it useful as a natural hedge or barrier plant in agricultural and homestead settings.

コウテイペンギン

世界最大のペンギンであるコウテイペンギン（Aptenodytes forsteri）は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
