The dominant animal species in the tundra is the Arctic fox. These small canids are incredibly well-adapted to the harsh conditions of the tundra ecosystem.
Arctic foxes have thick fur that insulates them against the freezing temperatures, and their small ears and rounded body shape help to minimize heat loss. They also have a diet that is opportunistic; while they primarily hunt small mammals like lemmings, they also scavenge on carrion and can even store food for later use when prey is scarce.
In addition to Arctic foxes, other notable animals include caribou, polar bears, and various migratory bird species that thrive during the brief Arctic summer. However, the Arctic fox stands out as particularly iconic due to its adaptability and prevalence in this ecosystem, making it a symbol of the tundra’s wildlife.
