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

Range

Distributed across Indonesia and Malaysia. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Emperor Penguin

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. 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.

Bornean orangutan

The world's largest arboreal mammal, Bornean orangutans weigh up to 90 kg and spend most of their lives in the rainforest canopy of Borneo. Solitary and semi-nomadic, they build nightly sleeping nests in trees and forage for fruit, leaves, and invertebrates. Critically Endangered, with populations having declined by over 50% in the past 60 years due to deforestation from palm oil expansion and illegal hunting.

Emperor Penguin

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.
