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.

Chucanti Salamander

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

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.

Chucanti Salamander

The Chucantí Salamander (Bolitoglossa chucantiensis) is a Critically Endangered plethodontid salamander known from the Chucantí mountain massif in the Darien region of eastern Panama. The genus Bolitoglossa represents the largest genus of salamanders globally, with the greatest diversity in Central and South America. B. chucantiensis was described from a small area of cloud forest at mid-to-high elevations in the Serranía de Majé range, an isolated and poorly surveyed mountain system in the Darién Province. Its Critically Endangered status reflects an extremely restricted range (estimated area of occupancy potentially under 10 km²), ongoing deforestation threatening its cloud forest habitat from agricultural expansion and cattle ranching, and the threat of chytridiomycosis, the amphibian fungal disease that has devastated salamander and frog populations across the Americas. Like other Bolitoglossa species, it is a direct-developing salamander that bypasses a free-swimming larval stage, laying eggs in moist terrestrial habitats. Conservation of the Chucantí Nature Reserve, established partly to protect the biodiversity of this mountain, is critical for the survival of this species.
