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.

Cloud Cisticola

Habitat

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

Range

Found in Norway.

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.

Cloud Cisticola

The cloud cisticola (Cisticola textrix) is a small passerine bird in the family Cisticolidae native to the grasslands of South Africa and Lesotho. It inhabits short open grasslands, karoo scrub, and montane grasslands at elevations up to 3,000 meters in the Drakensberg highlands, where males perform conspicuous high-altitude song flights that give the species its common name. The plumage is cryptically streaked brown and buff above, helping the bird blend into its grass habitat, with a short tail and fine bill adapted for insectivory. Like other cisticolas, C. textrix constructs a characteristic purse-shaped woven grass nest hidden deep within tussock grass. The species is endemic to southern Africa, with the core range centered on the South African highveld and Lesotho highlands. It feeds on small invertebrates gleaned from grass stems and the ground surface. Cloud cisticola populations face pressure from conversion and degradation of native grasslands through overgrazing, agricultural expansion, and inappropriate burning regimes affecting the open grassland habitats it requires throughout its southern African range.
