baleine bleue

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.

Clermont'S Spleenwort

Habitat

Typically found in moist, shaded forest floors and tropical canopies.

Range

Found in United States.

baleine bleue

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.

Clermont'S Spleenwort

Clermont's Spleenwort, Asplenium clermontiae, is a small fern in the family Aspleniaceae with a very restricted distribution in the Indian Ocean islands, believed to occur in the Mascarene archipelago. The genus Asplenium, the spleenworts, is one of the largest and most diverse fern genera globally, with species adapted to rock faces, tree bark, and moist forest floors across tropical, subtropical, and temperate regions. Clermont's Spleenwort, like many island-endemic Asplenium species, likely grows epiphytically on tree trunks or lithophytically on humid rock faces in montane forest, protected from the desiccating conditions of lower elevations. Island endemic ferns in the Mascarenes face severe threats from habitat loss driven by agricultural conversion, invasive plant species that alter forest structure, and introduced herbivores that destroy forest understory vegetation. Many spleenwort species have very small total populations confined to remnant forest patches. Asplenium clermontiae is considered rare and potentially threatened, though formal assessment data on its exact population size and trend are limited. Conservation of the species depends on the protection and restoration of humid forest habitats on the islands where it occurs.
