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.

coast club-rush

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Found in Guinea.

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.

coast club-rush

Coast club-rush (Schoenoplectus subulatus) is a tall, emergent sedge in the family Cyperaceae, found in coastal and estuarine wetlands throughout tropical and subtropical regions of Africa, Asia, the Middle East, and the Americas. It grows in brackish and freshwater tidal marshes, mangrove margins, river mouths, and lagoons, often forming dense stands in nutrient-rich mudflats. The triangular stems are characteristic of the Schoenoplectus genus, which includes the common bulrush. Like other bulrushes, coast club-rush provides dense nesting habitat for rails, herons, and bitterns, as well as food in the form of seeds and stems for waterfowl. It plays an important ecological role in coastal nutrient cycling, sediment trapping, and shoreline stabilisation. The IUCN assesses the species as Least Concern, reflecting its wide distribution across tropical and subtropical coastal regions globally. In some areas, it competes with other emergent vegetation, and its stands can be dense enough to impede water flow in managed wetlands. It is used in some regions for thatching and traditional basketry.
