Habitat & Geographic Range

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.

Le Criquet des mouillères

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

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.

Le Criquet des mouillères

<em>Euchorthippus declivus</em>, the common straw grasshopper, is an orthopteran insect in the family Acrididae, order Orthoptera. It is found primarily in dry grasslands, steppe habitats, and open scrubland across much of central and southern Europe and western Asia. The species is a typical grassland acridid, feeding on grasses and herbaceous plants, and is active during warmer months of the year. Males are notably smaller than females, and the species produces stridulatory sounds used in mate attraction, a characteristic of the family. <em>Euchorthippus declivus</em> plays an important role in grassland food webs as both herbivore and prey for birds, reptiles, and invertebrate predators. Geographic range data beyond its general European distribution remain incompletely documented at the global scale. Biological traits including average lifespan, body measurements under field conditions, and detailed dietary specificity remain poorly documented in the scientific literature. The species is currently assessed as Least Concern by the IUCN, indicating no immediate conservation threats, though grassland habitat loss across Europe may pose long-term pressures on local populations.
