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 Bell

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

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.

Colt's-foot Bell

<em>Epiblema sticticana</em>, the colts-foot bell moth, is a tortricid moth in the family Tortricidae with known occurrences in Belgium, Denmark, Norway, and Sweden. This species is assessed as Least Concern by the IUCN and occupies terrestrial and freshwater-associated habitats across its northern European range. The common name refers to the larval association with coltsfoot (<em>Tussilago farfara</em>) and possibly related Asteraceae, on which the caterpillars are believed to feed, a dietary habit typical of tortricid moths that specialise on particular host plant genera. Bell moths are named for the bell-shaped posture adults adopt when at rest on vegetation. <em>Epiblema sticticana</em> likely completes one or two generations per year within its temperate European range, with adults active during spring and summer months. The forewings typically display the intricate patterning of browns, greys, and strigulae characteristic of the genus, providing effective camouflage against bark and dead plant material. As a herbivorous insect, this species contributes to nutrient cycling through plant tissue consumption and serves as prey for insectivorous birds and bats. Biological traits of this species remain poorly documented in the scientific literature.
