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.

Russula subrubens is a mycorrhizal mushroom in the family Russulaceae, forming ectomycorrhizal associations with deciduous and coniferous trees. It produces medium-sized fruitbodies with reddish to pinkish caps and brittle white gills typical of the genus Russula. Assessed as Least Concern, it is found in temperate woodland habitats across Europe.
