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 Aloe-moss

Habitat

Inhabits temperate broadleaf and mixed forests and Mediterranean forests and woodlands within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found across Europe (6 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

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 Aloe-moss

<em>Aloina aloides</em>, commonly known as Common Aloe Moss, is a small moss in the family Pottiaceae. This species is classified as Critically Endangered on the IUCN Red List, representing a severe conservation concern with populations recorded across several European countries including Belgium, France, Germany, the Netherlands, and the United Kingdom. Common Aloe Moss typically inhabits open, disturbed, or sparsely vegetated ground in temperate and Mediterranean forest zones, often colonizing bare calcareous soils, chalk banks, old walls, and arable field margins. It forms small cushions or turfs of erect, spoon-shaped leaves that are distinctive for their inrolled margins and papillose surface. This moss is particularly associated with traditional low-intensity agricultural landscapes where bare ground is regularly created, and its dramatic decline is closely linked to the intensification of farming practices and the loss of suitable open, calcareous habitats across Europe. Biological traits of this species remain poorly documented in the scientific literature.
