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.

Suillus amabilis is a mycorrhizal bolete mushroom in the family Suillaceae, forming symbiotic associations with conifers, particularly pines. It produces colorful fruitbodies with a slimy cap surface and pores instead of gills on the underside, characteristic of the genus. Its mycorrhizal relationship is essential for nutrient exchange between fungus and host tree in forest ecosystems.
