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.

Colt's-foot Groundling

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, 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.

Colt's-foot Groundling

<em>Scrobipalpula tussilaginis</em>, the colts-foot groundling, is a gelechiid moth in the family Gelechiidae recorded from Belgium, Denmark, and Sweden, with occurrence in terrestrial and freshwater habitats. This species has not been evaluated by the IUCN. The common name indicates a larval association with coltsfoot (<em>Tussilago farfara</em>), a widespread ruderal Asteraceae of disturbed habitats, roadsides, and stream banks across temperate Europe. Gelechiid moths are a highly diverse family with the majority of species being leaf miners, stem borers, or seed feeders in their larval stage, making them important but often overlooked components of herbivore communities in temperate grasslands and disturbed habitats. <em>Scrobipalpula tussilaginis</em> adults are small, cryptically patterned moths, as is typical of the family Gelechiidae. Their small size and nocturnal habits make them difficult to survey without targeted light trapping or larval host-plant searches. The species likely completes a single generation per year in its northern European range. Biological traits of this species remain poorly documented in the scientific literature.
