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 virtually all terrestrial and freshwater habitats.

Range

Widely distributed across Asia (Japan, Taiwan), Europe (10 countries), and North America (United States).

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 parlatoria scale

<em>Parlatoria proteus</em> is an armored scale insect in the family Diaspididae, found in Japan, Taiwan, ten European countries, and the United States. It is a cosmopolitan pest species associated with a wide range of host plants across virtually all terrestrial habitats where cultivated trees and shrubs are present. The species infests the bark, leaves, and fruit of numerous hosts, including citrus, palms, figs, and ornamental plants, by piercing plant tissue and extracting sap. Infestations can lead to chlorosis, dieback, and fruit damage in heavily colonized plants. Female scale insects are sedentary once settled, protected beneath a waxy armored cover produced from molted exoskeletons and secretions. Males are short-lived winged forms involved only in reproduction. Conservation status has not been formally evaluated by the IUCN, consistent with its status as a widely distributed and economically significant agricultural pest rather than a species of conservation concern. Biological traits including average lifespan, body measurements, and detailed ecological dietary data remain poorly documented in standardized databases for this scale insect. <em>Parlatoria proteus</em> is managed through biological control agents, horticultural oils, and systemic insecticides in affected agricultural systems.
