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 Oak

Habitat

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

Range

Widely distributed across Africa (Lesotho, South Africa), Asia (Armenia, India), Europe (8 countries), North America (Canada, United States), Oceania and the Pacific (Australia, New Zealand), and South America (4 countries).

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 Oak

One of Europe's most important and widespread deciduous trees, the pedunculate oak can live over 1,000 years, reach 40 meters, and support the greatest biodiversity of any European tree species — over 2,300 species of insects, fungi, lichens, mosses, and birds directly depend on mature oaks. Found across Europe to western Asia in temperate forests, its hard, durable wood has been foundational to shipbuilding, architecture, and barrel making throughout history.
