Habitat & Geographic Range

Buckelwal

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.

Colorado hookless cactus

Habitat

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

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Colorado hookless cactus

<em>Sclerocactus glaucus</em>, the Colorado hookless cactus, is a small, barrel-shaped cactus in the family Cactaceae endemic to the Colorado River drainage basin in the western United States. This species is assessed as Least Concern by the IUCN, though it is listed as a threatened species under United States federal law, reflecting localised population pressures from habitat disturbance, off-road vehicle activity, and illegal collection. <em>Sclerocactus glaucus</em> inhabits diverse terrestrial environments including semi-arid shrublands, clay badlands, and river terraces at low to moderate elevations in Colorado and Utah. The species is characterised by its blue-green stem colour and the absence of the hooked central spines found in related species, a feature encoded in its common name. Flowers are typically pink to lavender and appear in spring. As a slow-growing perennial, this cactus is vulnerable to prolonged disturbance and recovery from population setbacks may require decades. Pollinators including native bees are essential for fruit and seed production. Biological traits of this species remain poorly documented in the scientific literature.
