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.

Scutellinia vitreola is a small cup fungus in the family Pyronemataceae, producing scarlet, disc-shaped apothecia fringed with stiff dark hairs along the margin that are diagnostic for the genus. It grows on moist, decaying wood, wet soil, and plant debris in humid forest environments. As a saprotrophic ascomycete, it contributes to the decomposition of lignocellulosic material on the forest floor.
