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 Greenshank

Habitat

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

Range

Distributed across Belgium, Denmark, Norway, Sweden, and 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.

Common Greenshank

<em>Tringa nebularia</em>, commonly known as the common greenshank, is a migratory wading bird belonging to the genus Tringa within the family Scolopacidae. This species occupies various aerial, terrestrial, and aquatic environments and has a documented range that includes Belgium, Denmark, Norway, Sweden, and Taiwan, reflecting its status as a long-distance migrant that breeds in northern Europe and winters across a broad range. Common greenshank is assessed as Least Concern on the IUCN Red List. The species is typically found along the edges of lakes, rivers, estuaries, and mudflats, where it forages for invertebrates and small fish using its slightly upturned bill. Biological traits of this species remain poorly documented in the scientific literature.
