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 Cottonwood

Habitat

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

Range

Widely distributed across Africa (South Africa), Asia (4 countries), Europe (17 countries), North America (United States), and South America (Brazil, Colombia).

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 Cottonwood

<em>Populus deltoides</em>, commonly known as common cottonwood or eastern cottonwood, is a large, fast-growing deciduous tree in the family Salicaceae. It is native to North America but has been widely planted and naturalized in Africa, Asia, Europe, and South America. Common cottonwood typically grows along rivers, streams, floodplains, and other moist bottomland habitats, where it can reach heights of 30 meters or more. The species is named for the cottony white fibers attached to its seeds, which are released in massive quantities in early summer and can create a snow-like appearance in the landscape. Its triangular, toothed leaves flutter characteristically in the slightest breeze due to their flattened petioles. Cottonwood is an important riparian tree providing habitat for birds, insects, and mammals. Biological traits of this species remain poorly documented in the scientific literature.
