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.

Chestnut Munia

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical coniferous forests spanning the Australasia and Indomalayan and Neotropic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Indonesia, Japan, United Arab Emirates), Europe (Norway, United Kingdom), North America (Haiti, Jamaica, United States), and South America (Colombia, Ecuador).

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.

Chestnut Munia

A small, sturdy estrildid finch with rich chestnut-brown plumage, black head, and white belly, chestnut munias inhabit grasslands, rice paddies, and open forest edges from India and Sri Lanka east through Southeast Asia to the Philippines and Taiwan. Highly gregarious, they form large flocks and are sometimes considered minor agricultural pests on rice crops. Widely kept as aviary birds across Asia, they are relatively easy to breed and maintain in captivity.
