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.

Lecanographa lyncea is a rare, crustose lichen that grows on the bark of ancient, veteran trees in old-growth woodland. It produces elongated lirellate apothecia and is considered one of the most sensitive indicators of undisturbed, long-continuity forest ecosystems in Europe. Critically Endangered, it faces severe threat from habitat loss, veteran tree decline, and air pollution.
