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.

Chisos Mountain Hedgehog Cactus

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。

Chisos Mountain Hedgehog Cactus

The Chisos Mountain Hedgehog Cactus (Echinocereus chisosensis) is a rare, small columnar cactus endemic to the Chisos Mountains of Big Bend National Park in Brewster County, Texas, USA. It belongs to the family Cactaceae and genus Echinocereus, the hedgehog cacti, characterised by their ribbed, cylindrical stems densely armed with radiating spines and their showy funnel-shaped flowers. This species produces striking magenta to rose-pink blooms in spring, which open during the day to attract native bee pollinators. The Chisos Mountain Hedgehog Cactus grows on rocky limestone slopes and cliffs at elevations between approximately 1,500 and 2,200 metres, where it is adapted to thin, well-drained soils and the region's semi-arid climate with seasonal summer monsoon rainfall. Its extremely restricted range — estimated at fewer than 2,000 individuals across a handful of localities — makes it highly vulnerable to stochastic events, illegal collection, and climate-driven habitat change. The IUCN classifies it as Endangered. Conservation challenges include not only its tiny range but also slow reproductive rates typical of cacti; plants may take many years to reach reproductive maturity. Big Bend National Park provides some protection, though illegal cactus poaching for the horticultural trade remains a concern for all rare Chihuahuan Desert endemics.
