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 Rose-Mallow

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Distributed across Brazil, Romania, 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 Rose-Mallow

<em>Hibiscus moscheutos</em>, commonly known as the common rose mallow, is a flowering plant in the family Malvaceae. Native to wetlands and marshy areas across eastern North America, this herbaceous perennial has been introduced and naturalized in parts of Brazil, Romania, and Taiwan. The species typically inhabits freshwater marshes, riverbanks, pond margins, and moist meadows, thriving in full sun to partial shade conditions. It produces large, showy flowers that can reach up to 30 centimeters in diameter, typically displaying white, pink, or red petals with a distinctive dark center. The plant can grow up to 2.5 meters in height under favorable conditions. Common rose mallow is assessed as Least Concern on the IUCN Red List, reflecting its wide distribution and stable populations across its native and introduced ranges. It tolerates flooding and temporarily waterlogged soils, making it well adapted to riparian ecosystems. The species is pollinated primarily by bees and other large insects attracted to its prominent blooms. Biological traits such as average lifespan, typical body measurements, and diet remain poorly documented in standardized ecological databases. In cultivation, it is widely grown as an ornamental plant, valued for its dramatic flowers and adaptability to garden settings.
