löchriger Geweihschwamm

<em>Axinella polypoides</em>, commonly known as the Common Antlers Sponge, is a marine sponge in the family Axinellidae. This species has not been formally evaluated by the IUCN and has been recorded in waters off Norway, among other European marine environments. The Common Antlers Sponge is an erect, branching sponge that typically forms irregularly branched, tree- or antler-like colonies in yellow to orange coloration, which are visually distinctive on the rocky substrates of the Mediterranean Sea and the northeastern Atlantic Ocean. It typically grows attached to hard substrates such as rocks and corals in subtidal zones, often in areas with moderate to strong water currents that deliver particulate food. As a filter feeder, it draws water through its porous body to extract organic particles and microorganisms. This sponge can reach substantial sizes and is often found in deeper, clear-water habitats. Biological traits of this species remain poorly documented in the scientific literature.

Eisbär

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
