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 Glider

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (19 countries).

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 Glider

<em>Neptis sappho</em>, commonly known as the common glider, is a butterfly in the family Nymphalidae. The species has a broad European distribution, with documented occurrences in 19 countries across the continent. <em>Neptis sappho</em> typically inhabits woodland edges, clearings, and scrubby areas where its larval host plants, primarily species of legumes such as <em>Lathyrus</em> and <em>Vicia</em>, are available. The species is assessed as Least Concern, reflecting its reasonably wide distribution across temperate and sub-Mediterranean Europe. The common glider is named for its characteristic flight pattern, which involves alternating periods of gliding and flapping, producing a distinctive sailing motion through woodland habitats. Its wings are dark brown with white bands and spots that create a striking pattern visible during flight. Biological traits of this species remain poorly documented in the scientific literature. The species typically produces one or two generations per year depending on latitude and climate, and adults are often observed nectaring at flowers in sunny woodland clearings and along forest margins.
