Polar bear

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Eggerelloides medius is a benthic foraminiferan, a single-celled marine organism constructing a multi-chambered agglutinated test from sediment particles. It inhabits fine-grained marine sediments in shallow to moderate depth coastal environments. Like other foraminifera, it feeds on detritus and bacteria and plays a role in benthic biogeochemical cycling, including organic matter remineralisation.

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.
