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.

Poseidonia is a genus of archaea within the class Halobacteria, characterized by its inhabitants of hypersaline environments. Members of this genus are adapted to extreme salt concentrations and contribute to the biogeochemical cycling of carbon and nitrogen in salt lakes and brines. The group has not been evaluated under conservation criteria.
