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 Birch

Habitat

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

Range

Widely distributed across Africa (South Africa), Europe (6 countries), North America (Canada, United States), Oceania and the Pacific (Australia, New Zealand), and South America (Argentina).

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 Birch

The common birch (<em>Betula pendula</em>), also known as the silver birch, is a deciduous tree with a broad distribution spanning Africa, Europe, North America, Oceania, and South America. Countries in its range include South Africa, several European nations, Canada, the United States, Australia, New Zealand, and Argentina. It is classified as Least Concern on the IUCN Red List. <em>Betula pendula</em> typically grows in a wide variety of terrestrial habitats from tropical lowlands to temperate montane forests, demonstrating considerable ecological versatility. The tree is easily recognized by its slender form, pendulous branches, and distinctive white or silvery bark that peels in papery strips. It is often a pioneer species, rapidly colonizing disturbed and open ground. Common birch plays an important ecological role as a habitat and food source for numerous insects, birds, and fungi. Its wood is valued for furniture, flooring, and plywood production. Biological traits of this species remain poorly documented in the scientific literature.
