Polar bear

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.

Pseudoxanthomonas mexicana is a Gram-negative bacterium first isolated in Mexico and belonging to the family Xanthomonadaceae. It inhabits soil and possibly plant-associated environments, where it may play roles in organic matter decomposition. Members of this genus are often noted for their production of yellow pigments and various hydrolytic enzymes.
