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 tsessebe

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

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 tsessebe

<em>Damaliscus lunatus</em>, commonly known as the common tsessebe, is a large antelope in the family Bovidae, endemic to the grasslands and open savannas of sub-Saharan Africa. This species is among the fastest antelopes in Africa, capable of reaching speeds exceeding 80 kilometers per hour when fleeing predators. <em>Damaliscus lunatus</em> is typically found in moist, medium-height grasslands and floodplain grasslands, often near permanent water sources, across countries including Botswana, Zimbabwe, Zambia, Tanzania, and South Africa. The coat is a rich reddish-brown with a distinctive darker patch on the shoulders and upper hindquarters, and both sexes bear lyrate, heavily ridged horns. Tsessebe are highly selective grazers, favoring short to medium-height grasses, and they typically form herds that may number from a few individuals to several hundred during seasonal migrations. The species is currently assessed as Vulnerable by the IUCN, with populations declining due to habitat loss, hunting, and competition with livestock across much of its former range. Conservation efforts are focused on maintaining large protected grassland areas and managing livestock encroachment. Biological traits such as average lifespan, body weight, and body length are consistent with large bovid norms but precise population-wide figures remain poorly documented in the scientific literature.
