Populations are also found in montane and highland environments at higher elevations.

Range

Found in Norway. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Hausmaus

Habitat

Range

Widely distributed across Africa (9 countries), Asia (13 countries), Europe (41 countries), North America (14 countries), Oceania and the Pacific (12 countries), and South America (10 countries).

Kaiserpinguin

The world's largest penguin, emperor penguins stand up to 1.2 meters and weigh 45 kg, inhabiting the Antarctic continent in some of the most extreme conditions on Earth. They breed in midwinter darkness at temperatures below -60°C, with males incubating single eggs on their feet under a brood pouch for 65 days while females are at sea. Their huddling behavior — cycling individuals through the warm center of thousands-strong groups — is a masterclass in cooperative survival.

Hausmaus

Among the most widespread and numerous mammals on Earth, house mice originated in South Asia and have accompanied human civilization across every continent except Antarctica. Weighing just 15–25 g, they are highly adaptable omnivores capable of surviving on minimal food and water. As the world's most commonly used laboratory animal, the house mouse has contributed to virtually every branch of biomedical research. They cause significant agricultural damage globally.
