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 Marsh Bedstraw

Habitat

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

Range

Widely distributed across Europe (8 countries), North America (Canada, 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 Marsh Bedstraw

<em>Galium palustre</em>, the common marsh bedstraw, is a scrambling herbaceous plant in the family Rubiaceae, distributed across Europe, North America, and Oceania. It is classified as Least Concern on the IUCN Red List. This species typically grows in wetland habitats including fens, marshes, wet meadows, ditches, and the margins of rivers and ponds, where it climbs through taller vegetation using tiny hooked bristles on its stems and leaves. Common marsh bedstraw produces small, white, four-petalled flowers in loose clusters during summer months. Like other members of the genus Galium, its stems are distinctively square in cross-section. The plant plays a modest role in wetland ecosystems, providing cover for invertebrates and contributing to the structural complexity of marginal vegetation. Its widespread distribution across three continents and tolerance for a range of wetland conditions contribute to its secure conservation status. The species has limited documented economic uses but is ecologically representative of healthy freshwater marginal habitats.
