Wasserkastanie

The Chinese Water Chestnut (Eleocharis dulcis) is a species in the genus Eleocharis. It is currently classified as Least Concern on the IUCN Red List. Native to Comoros, Guinea, Madagascar, Mauritius, and Micronesia.

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.
