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 Orange Lichen

Habitat

Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Denmark, Norway, Portugal, Sweden, and 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 Orange Lichen

<em>Xanthoria parietina</em> is a foliose lichen in the family Teloschistaceae, one of the most conspicuous and widely recognized lichens across Europe and North America. It is recorded in Denmark, Norway, Portugal, Sweden, and the United States. The species typically colonizes bark, rock surfaces, walls, roof tiles, and other exposed substrates in nutrient-enriched environments. Its vivid orange to yellow-orange thallus is produced by the pigment parietin, which functions as a photoprotective compound shielding the lichen from UV radiation. <em>Xanthoria parietina</em> is considered a nitrophilous species, thriving in habitats enriched by nitrogen compounds, such as those near bird roosting sites, agricultural areas, and urban zones. It is highly tolerant of air pollution and is frequently used as a bioindicator in ecological studies. The IUCN lists this species as Least Concern given its broad distribution and tolerance of disturbed environments. As a lichen, it is a mutualistic association between a fungal partner and algal or cyanobacterial photobionts. Biological traits such as growth rates, lifespan, and dietary ecology remain poorly documented in standardized databases for lichen species.
