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.

Zebra Finch

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Widely distributed across Europe (8 countries), Oceania and the Pacific (Australia), 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.

Zebra Finch

One of the most popular cage birds worldwide, zebra finches are small, seed-eating songbirds native to arid and semi-arid grasslands across mainland Australia and the Lesser Sunda Islands. Males display distinctive orange cheek patches, red beaks, and barred flanks. Highly social, living in flocks that may number thousands in the wild, zebra finches are fundamental model organisms in neuroscience research on vocal learning, song development, and the neural basis of learning and memory.
