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 Pouchwort

Habitat

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

Range

Widely distributed across Asia (Taiwan), Europe (6 countries), and North America (United States). Currently classified as Vulnerable 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 Pouchwort

The Common Pouchwort, <em>Calypogeia fissa</em>, is a liverwort in the family Calypogeiaceae, a group of non-vascular plants within the division Marchantiophyta. It is a leafy liverwort characterized by its creeping, pale green to yellowish shoots bearing overlapping, asymmetric leaves arranged in two lateral rows and a row of smaller underleaves. The species is typically found growing on moist, acidic soil, rotting wood, and shaded banks in temperate forests and moorlands. Its geographic range encompasses Asia, Europe, and North America, where it occupies humid woodland habitats and montane environments with stable moisture regimes. <em>Calypogeia fissa</em> reproduces both sexually via spores and vegetatively through gemmae, which are small propagules produced in specialized cups at shoot tips. As a bryophyte, it lacks true roots, stems, and leaves in the vascular sense, absorbing water and nutrients directly through its surface. The species is assessed as Vulnerable on the IUCN Red List, reflecting concerns about habitat loss and the degradation of moist woodland environments across parts of its range. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
