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.

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Belgium, Denmark, 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.

Clitocybe marginella is a small agaric fungus in the family Tricholomataceae found in temperate European woodland and semi-open habitats. Like many members of the diverse Clitocybe genus, it produces modest fruiting bodies with a depressed to funnel-shaped cap and decurrent gills running down the stipe, typically whitish to pale buff in coloration. The species fruits in autumn, colonizing leaf litter, humus-rich soils, and woodland margins where it functions as a saprotrophic decomposer. The epithet marginella may reference subtle marginal features of the cap or gills that help distinguish it from closely related species. Identification within this genus typically requires microscopic examination of spore size and shape, along with assessment of odor, taste, and substrate preferences. European Clitocybe diversity is significant, with dozens of species recorded across forest, grassland, and heathland habitats. C. marginella contributes to the intricate web of decomposer fungi that recycle nutrients in temperate forest ecosystems throughout Northwestern and Central Europe.
