elk

Also known as the red deer, elk are among the largest members of the deer family, with antlered males reaching up to 240 kg. Found across temperate forests and grasslands of Europe, Asia, and North America, where populations were historically separated as distinct subspecies. Males shed and regrow their antlers annually, engaging in dramatic roaring contests during autumn rut. An important game and conservation species across its range.

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.
