Habitat & Geographic Range

大翅鯨

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 (5 countries), and South America (Colombia, Ecuador, Venezuela). 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.

大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

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.
