Common animals found in the Arctic include polar bears, seals, arctic foxes, and various species of migratory birds. Polar bears, for instance, are iconic for their role in the Arctic ecosystem, adapting to harsh conditions with thick fur and fat layers for insulation. Seals are crucial for the polar food chain, providing sustenance for larger predators like polar bears. The Arctic is also home to unique species that have adapted to extreme temperatures and seasonal changes, often exhibiting behaviors or physical traits that enable them to thrive in icy habitats. These animals contribute significantly to the biodiversity of this fragile environment.
