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.

Nemania serpens is a saprotrophic ascomycete fungus producing flat, black, crust-like stromata that creep along the surface of dead wood, particularly hardwood branches and logs. It is found across temperate forests in Europe and North America, where it plays a role in wood decomposition. This species is one of the more commonly encountered wood-inhabiting ascomycetes in deciduous woodland.
