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.

Compressed Flapwort

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Belgium, Norway, and Sweden.

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.

Compressed Flapwort

<em>Nardia compressa</em>, commonly called the Compressed Flapwort, is a leafy liverwort in the family Jungermanniaceae, a lineage of non-vascular land plants (division Marchantiophyta) that diverged from other embryophytes over 400 million years ago. This small, mat-forming bryophyte typically colonizes moist, acidic substrates along stream banks, seepages, and wet rock faces in cool-temperate habitats throughout Europe. Its flattened, overlapping leaves give the plant a compressed appearance, which inspired both its common and scientific names. Like all liverworts, <em>Nardia compressa</em> lacks true vascular tissue and absorbs water and nutrients directly through its leaf surfaces, deriving energy through photosynthesis rather than heterotrophic feeding. The species has been recorded in Belgium, Norway, and Sweden, suggesting an affinity for the moist, boreal and Atlantic climatic zones of northwestern and northern Europe. It is currently assessed as Least Concern by the IUCN, indicating no immediate extinction risk across its known range. Biological traits including individual lifespan, reproductive rates, and specific growth measurements remain poorly documented relative to vascular plant species, though liverworts are generally slow-growing perennial organisms tightly dependent on stable moisture regimes.
