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 Marbled Carpet

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (4 countries) and North America (Canada, United States).

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 Marbled Carpet

<em>Dysstroma truncata</em>, the common marbled carpet, is a geometrid moth in the family Geometridae distributed across Europe and North America. It is classified as Least Concern on the IUCN Red List, reflecting stable populations across its wide temperate range. The species is typically found in woodland, hedgerow, and garden habitats where its larval food plants are present. Its wings display complex, marbled patterns in shades of brown, grey, and white, providing effective camouflage against tree bark and leaf litter. Adults are typically nocturnal and are recorded from spring through autumn, with multiple generations possible in warmer parts of its range. Larvae feed on a variety of deciduous plants including bilberry, heather, and various shrubs. The common marbled carpet is a familiar species to moth recorders across temperate Europe and North America, where it is frequently encountered at light traps. Its widespread distribution and habitat generalism contribute to its secure conservation status across both continents.
