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.

Derber Korkstacheling

Hydnellum compactum is a stipitate, tooth fungus with a compact, brownish-orange to rusty-brown cap surface covered in spines on the underside. It grows on the forest floor in coniferous forests across Europe and parts of North America, forming ectomycorrhizal associations with trees. This fungus obtains nutrients by forming mutualistic partnerships with the roots of pine, spruce, and fir trees.
