Habitat & Geographic Range

blue whale

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 Wood-Rush

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Widely distributed across Africa (South Africa), Asia (Taiwan), Europe (7 countries), North America (United States), and Oceania and the Pacific (Australia).

blue whale

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

Common Wood-Rush

<em>Luzula multiflora</em>, the common wood rush, is a perennial herbaceous plant in the family Juncaceae. It has a broad, nearly cosmopolitan distribution, occurring across Europe, Asia, North America, and parts of the Southern Hemisphere, where it grows in a wide range of habitats including meadows, heathlands, open woodlands, grasslands, and mountain slopes. The species typically forms tufted clumps of grass-like leaves that are sparsely hairy along the margins, a characteristic shared by many members of the genus. Flowering stems reach roughly 10–40 cm in height and bear dense clusters of small brown flowers arranged in rounded heads. It thrives in well-drained to moderately moist, often acidic soils and tolerates a wide range of light conditions from full sun to partial shade. Biological traits such as average lifespan, precise body measurements, and detailed population data remain poorly documented in consolidated scientific literature. <em>Luzula multiflora</em> plays an ecological role in many grassland and heathland communities, providing ground cover and contributing to soil stability. It is assessed as Least Concern given its wide distribution and abundance across multiple continents.
