Joubarbe des toits

<em>Sempervivum tectorum</em>, commonly known as the common houseleek or hen and chicks, is a succulent perennial in the family Crassulaceae. It is classified as Least Concern on the IUCN Red List, with a broad distribution spanning Asia (including Taiwan), 17 European countries, and North America. The species typically grows on rocky outcrops, old walls, rooftops, and dry, well-drained soils in temperate and montane environments. Adapted to harsh, nutrient-poor conditions, it has been cultivated for centuries as both an ornamental and a plant with traditional medicinal uses. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.

Manchot empereur

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.
