Arctic biodiversity refers to the variety of life forms found in the Arctic region, including plants, animals, and microorganisms. This unique ecosystem is characterized by extreme cold, ice-covered landscapes, and long periods of darkness. Species such as polar bears, walruses, and Arctic foxes are adapted to survive in these harsh conditions, while various migratory birds visit during the summer months. The Arctic also hosts diverse marine life, including whales, seals, and numerous fish species. The region's fragile ecosystems are interconnected, with changes in one area affecting others. Climate change poses significant threats to Arctic biodiversity, leading to habitat loss and shifts in species distribution.
