Lemmings are small mouse-like animals that live in the Arctic tundra. In summer they are brown, but in winter they are all white. Their white winter coats help them to hide from the Snowy Owl and other predators that depend upon them for food.
These little critters live in colonies. In summer, that's a maze of tunnels and passageways through the tundra vegetation. Lemmings are a favorite food of many Arctic animals, and the tunnels provide some protection as they move about - and help to hide their nests.
Warning: The tunnels can make the ground unstable and difficult to walk on - you might fall through a maze and sink up to you knees!
Winter doesn't slow the lemmings down - they're active all year round. They grow longer front claws in the winter to dig tunnels under the wind-packed snow. They live there, continuing to search out food and bear their young, while protected from the cold and their predators.
