Habitat & Geographic Range

African Penguin

Habitat

Typically found in diverse ecosystems where prey species are available.

Range

Found in Norway. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its 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.

African Penguin

The only penguin species native to Africa, African penguins inhabit islands and coastlines of southern Africa from Namibia to Port Elizabeth. Reaching 70 cm in height, they are recognized by their braying, donkey-like calls and distinctive black-and-white plumage with a unique pink gland above the eye. Endangered, with populations having declined by 70% since 2000 due to food scarcity from commercial fishing, oil spills, and climate-driven shifts in prey distribution.

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.
