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 Marsupial Frog

Habitat

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

Range

Found in Venezuela. 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 Marsupial Frog

<em>Gastrotheca ovifera</em>, the common marsupial frog, is a tree frog in the family Hemiphractidae, endemic to Venezuela. It is classified as Vulnerable on the IUCN Red List, reflecting population declines associated with habitat loss and degradation. This species is typically found in freshwater environments, moist montane forests, and wetland habitats within Venezuela's highlands. The common marsupial frog takes its name from the female's dorsal brood pouch, in which fertilized eggs are carried and develop until the young emerge as advanced tadpoles or juvenile froglets. This reproductive adaptation reduces dependence on standing water for larval development and provides protection for the developing young. Like other members of the family Hemiphractidae, this species is associated with humid forest environments where moisture is reliably available. Deforestation and agricultural expansion in Venezuela's montane forest habitats represent significant threats to this and related species. Detailed data on population estimates, lifespan, and body measurements for this species remain limited in current scientific literature.
