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 Thin-toed Frog

Habitat

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

Range

Found in Venezuela.

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 Thin-toed Frog

<em>Leptodactylus leptodactyloides</em>, the common thin-toed frog, is an amphibian in the family Leptodactylidae, primarily recorded from Venezuela and surrounding lowland regions of northern South America. It is classified as Least Concern on the IUCN Red List. This terrestrial frog typically inhabits savanna grasslands, gallery forests, and disturbed areas adjacent to wetlands, where it breeds in temporary pools and flooded grasslands during the rainy season. Like other leptodactylid frogs, males call from the water's edge to attract females, and the species produces foam nests for eggs. Diet typically consists of invertebrates including insects, spiders, and worms. The species is part of a diverse and taxonomically complex genus, and population status across its range is not precisely quantified. Biological traits such as adult body length, weight, lifespan, and clutch size remain poorly documented in comprehensive standardized scientific assessments for this species specifically. Conservation efforts benefit from broader amphibian monitoring programs across Venezuela and the surrounding region.
