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 terrestrial and aquatic habitats including forests and freshwater.

Range

Found across Asia (Turkey) and Europe (5 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 pelican’s foot

<em>Aporrhais pespelecani</em>, commonly known as the common pelican's foot, is a marine gastropod mollusk belonging to the family Aporrhaidae. This distinctive snail is named for its unusual shell shape, which features a flared outer lip with finger-like projections resembling a pelican's webbed foot. It inhabits sandy and muddy substrates of shallow coastal seas, typically found at depths ranging from the intertidal zone to several hundred metres. The species is distributed across temperate European waters, with confirmed records from Belgium, Denmark, Norway, and Sweden, as well as Turkey, indicating a range spanning the northeastern Atlantic and parts of the Mediterranean and Black Sea. <em>Aporrhais pespelecani</em> typically buries itself partially in soft sediments, where it feeds on organic detritus and microalgae. The species is assessed as Least Concern on the IUCN Red List, reflecting its relatively wide distribution and absence of major threats. Biological traits such as average lifespan, body size, and detailed dietary composition remain poorly documented in the scientific literature. Populations are generally considered stable, though localised habitat degradation from coastal development and trawling may pose risks in certain parts of its range.
