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.

Viridibacillus arenosi is a spore-forming bacterium isolated from sandy soils, as its species name suggests. It forms characteristic oval endospores and is distinguished by its ability to grow in relatively nutrient-poor sandy substrates. This aerobic chemoheterotroph plays a role in organic matter decomposition in sandy terrestrial environments.
