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 Damselbug

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

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 Damselbug

<em>Nabis rugosus</em>, the common damselbug, is a predatory true bug in the family Nabidae. This species is distributed across Belgium, Denmark, Norway, and Sweden, typically inhabiting a broad range of terrestrial and freshwater environments including grasslands, agricultural fields, hedgerows, and the margins of wetlands. The common damselbug is a generalist predator, often feeding on small arthropods such as aphids, caterpillars, and other soft-bodied invertebrates. It uses its raptorial forelegs to capture prey and possesses piercing mouthparts for consuming body fluids. <em>Nabis rugosus</em> is typically slender and brownish in coloration, offering effective camouflage among grasses and vegetation. The species completes multiple generations per year in suitable climates and is considered an important natural control agent in agricultural settings. Its conservation status is assessed as Least Concern, reflecting stable populations across its European range. Beyond these documented traits, additional biological characteristics of this species are not extensively detailed in the available scientific literature.
