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.

Pannaria rubiginosa is a foliose lichen in the family Pannariaceae, formerly found growing on bark and mossy rocks in humid temperate forests. It is assessed as Extinct (EX) on the IUCN Red List, having disappeared from its known localities due to habitat loss and air pollution.
