clusterleaf

Terminalia sericea, known as clusterleaf or silver terminalia, is a medium-sized deciduous tree in the family Combretaceae native to the savanna woodlands and bushveld of southern Africa, ranging from South Africa through Zimbabwe, Botswana, Namibia, and into Zambia and Mozambique. The species is a characteristic and abundant component of the broad-leaved miombo and mopane woodland systems of the region. Trees typically reach 6–12 meters in height, distinguished by their distinctive silvery-grey leaves clustered at branch tips, which account for the common name clusterleaf. The leaf undersides are covered with fine silky hairs giving a silver sheen that is particularly visible in sunlight and dry season conditions. Terminalia sericea is prized for its dense, durable hardwood, and extracts from the roots, bark, and leaves have extensive applications in traditional African medicine, being used to treat infections, stomach complaints, and malaria symptoms. Pharmacological research has confirmed antimicrobial and anti-inflammatory properties in the species. It produces small, winged fruits that are wind-dispersed across the savanna landscape. The species is assessed as Least Concern by the IUCN and remains common and widespread across its southern African range.

Common Seal

最も広く分布する鰭脚類であるゴマフアザラシの近縁種・ゼニガタアザラシ（Phoca vitulina）は、北大西洋と北太平洋の温帯・亜北極沿岸に生息する。成体は最大130kgに達し、海での魚・イカ・甲殻類の捕食と海岸や岩場での休息にほぼ同じ時間を費やす。大きく表情豊かな目は低照度での水中視覚に適応している。シャチ・サメ・ホッキョクグマにとって重要な食料源である。
