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 Leaf Weevil

Habitat

Found across multiple habitat types including temperate coniferous forests, montane grasslands and shrublands, and deserts and xeric shrublands within the Palearctic biogeographic realm.

Range

Found across Asia (4 countries) and Europe (33 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 Leaf Weevil

The Common Leaf Weevil (<em>Phyllobius pyri</em>) is a beetle in the family Curculionidae, classified as Least Concern on the IUCN Red List. It is native to four Asian countries and thirty-three European countries, giving it one of the broadest distributions of any weevil species in the Palearctic biogeographic realm. The species typically inhabits temperate coniferous forests, montane grasslands, shrublands, and deserts and xeric shrublands across its extensive range. Adults are typically covered in metallic green or bronze scales that give them a distinctive appearance. They feed on the foliage of a wide range of deciduous trees and shrubs, with larvae developing in the soil where they feed on roots. The Common Leaf Weevil is occasionally regarded as an agricultural and horticultural pest due to its feeding on fruit trees and ornamental plants. Its vast European and Asian range and generalist feeding habits support its Least Concern assessment. Biological traits of this species remain poorly documented in the scientific literature.
