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 filbert

Habitat

Inhabits Mediterranean forests and woodlands within the Palearctic biogeographic realm.

Range

Widely distributed across Asia (Cyprus, Iraq), Europe (7 countries), North America (Canada, United States), and South America (Brazil).

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 filbert

<em>Corylus avellana</em> is a deciduous shrub or small tree in the family Betulaceae, order Fagales, commonly known as the common hazel or common filbert. The species is classified as Least Concern on the IUCN Red List, with widespread and stable populations across its native and introduced range. <em>Corylus avellana</em> is native to Europe and western Asia and has been introduced to parts of North America and South America. It is particularly associated with temperate deciduous woodlands, hedgerows, and scrubland across the Mediterranean forests and the Palearctic realm. The species typically forms a multi-stemmed shrub with broad, rounded leaves and catkins that emerge in late winter before the leaves appear, representing one of the earliest flowering events of the temperate year. Hazel nuts produced by this species are an important food source for woodland wildlife including squirrels, dormice, and woodpeckers. The species has been cultivated for centuries for nut production and coppicing. Biological traits of this species remain poorly documented in the scientific literature.
