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, Portugal, 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 agrestis is a small, pale agaric fungus in the family Tricholomataceae found across Western and Northern Europe, recorded from Belgium, Denmark, Norway, Portugal, and Sweden. It typically inhabits open grassy habitats including meadows, pastures, lawns, and roadsides, fruiting in autumn when moisture conditions are favorable. The cap is whitish to pale buff, often inrolled when young and becoming broadly flattened to slightly funnel-shaped with age, with crowded, decurrent gills and a short cylindrical stipe. The genus Clitocybe is characterized by the funnel-shaped or depressed cap and decurrent gill arrangement that gives many species a distinctive appearance. C. agrestis is a saprotrophic decomposer, breaking down plant litter and organic matter in grassland soils. It may be confused with toxic Clitocybe species, making accurate identification important. The species is listed as Least Concern, though European grassland fungi broadly face pressure from agricultural intensification, nitrogen deposition, and conversion of diverse meadows to monoculture pastures.
