Amerikanische Apfelschnecke

<em>Pomacea bridgesii</em>, commonly known as the Common Apple Snail or Spike-topped Apple Snail, is a freshwater gastropod mollusk in the family Ampullariidae. This species is classified as Least Concern on the IUCN Red List and has an extensive global distribution spanning Asia, Europe, North America, and South America, largely due to its popularity in the aquarium trade and subsequent introductions. In its native South American range, Common Apple Snails typically inhabit tropical and subtropical freshwater environments including rivers, lakes, marshes, and flooded forests such as mangroves. They are known for their distinctly globular shell and their ability to breathe both air and water using a combination of a gill and a primitive lung-like structure. This species typically lays distinctive pink egg clutches above the waterline on emergent vegetation or hard surfaces. It feeds primarily on aquatic vegetation, algae, and detritus. Its average lifespan is approximately 3 years under favorable conditions.

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.
