Knoblauchkröte

<em>Pelobates fuscus</em>, the common Eurasian spadefoot toad, is a fossorial amphibian in the family Pelobatidae, listed as Critically Endangered by the IUCN Red List, reflecting severe population declines and an urgent conservation status across its range. The species is documented in Belgium, Denmark, Luxembourg, Russia, and Sweden, and is associated with multiple biome types in the Palearctic region, typically favoring sandy, loose soils in agricultural landscapes, sandy heathlands, and open forests that facilitate its burrowing lifestyle. <em>Pelobates fuscus</em> spends the majority of its life underground, emerging primarily during the breeding season in spring to migrate to shallow, well-vegetated ponds, ditches, and slow-moving waterbodies for reproduction. The species is characterized by its smooth, mottled skin, large golden or yellowish eyes with vertical pupils, and the hardened metatarsal tubercle on each hind foot that serves as a digging tool. Tadpoles of this species are unusually large and can take up to five months to metamorphose. Primary threats include habitat loss through land-use change, drainage of breeding ponds, agricultural intensification, road mortality during migration, and degradation of sandy habitats essential for burrowing. Conservation efforts focus on habitat restoration and the creation of wildlife corridors. Biological traits of this species remain poorly documented in the scientific literature.

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.
