Habitat & Geographic Range

藍鯨

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Spike-thorn

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

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.
