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.

Cockspur coral tree

Habitat

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

Range

Widely distributed across Africa (Eswatini, Libya, Seychelles), Asia (India, Taiwan, Turkey), Europe (Portugal), North America (United States), Oceania and the Pacific (Australia), 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.

Cockspur coral tree

The cockspur coral tree (Erythrina crista-galli) is a striking deciduous tree in the family Fabaceae native to the warm-temperate and subtropical riverbanks, gallery forests, and seasonally flooded grasslands of South America, particularly in Argentina, Uruguay, Brazil, and Paraguay. It has been widely planted and naturalised worldwide in warm climates as an ornamental, chosen for its spectacular racemes of vivid scarlet, claw-shaped flowers — borne on thorny stems before or alongside the new leaves — that attract hummingbirds and other nectarivores. The species name crista-galli means cock's crest in Latin, describing the red comb-like flower shape. Growing to 5–10 metres, the tree develops a gnarled, spreading crown and thick, spongy bark. In Argentina, E. crista-galli is the national tree — known locally as ceibo — and the ceibo flower is the national flower, celebrated in art, literature, and folklore. The tree's hollow, water-filled stems and lightweight wood allow it to survive periodic flooding; in southern Brazil it is characteristic of the pantanal and riverine woodland ecosystems. Pods containing bright red seeds — toxic if ingested — split when mature. The bark and flowers have traditional medicinal uses in South American folk medicine. Erythrina crista-galli is classified as Least Concern by the IUCN given its wide native distribution and extensive cultivation globally.
