Olivbrauner Rötling

Entoloma versatile is a small to medium-sized Entoloma mushroom with variable coloration in shades of grey, brown, or olive, and the characteristic pink spore print of the genus. It grows in grasslands, woodland edges, and scrubby habitats across temperate Europe. Near Threatened, its rarity is linked to the decline of ancient, unimproved grasslands under agricultural intensification.

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.
