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.

Coast Coral Tree

Habitat

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

Range

Found in Taiwan.

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.

Coast Coral Tree

Coast coral tree (Erythrina caffra) is a large, semi-deciduous tree in the family Fabaceae, native to the subtropical coastal forests and riparian zones of the eastern coast of South Africa and coastal Mozambique. It grows in coastal dune forest, riverine forest margins, and rocky hillsides near the sea, often becoming a prominent canopy tree in coastal forest. The trunk is covered in distinctive corky, spiny bark; branches are armed with short thorns; and spectacular clusters of bright red, tubular flowers are produced before or with the new leaves in late winter and spring, providing an important nectar source for sunbirds and other nectarivores. Fruit pods are long, woody, and contain bright red seeds. Coast coral tree is widely planted as a street tree, shade tree, and garden specimen across subtropical coastal cities and is the official tree of Durban, South Africa. It is assessed as Least Concern by the IUCN. Historically, various parts of the tree were used medicinally by Zulu and Xhosa communities. In cultivation it has naturalised in Hawaii and other tropical regions.
