"Our first wildlife! That white rodent you just saw was a lemming, and it's the smallest mammal you'll see here. They manage to survive during the cold winter by eating plants, grasses, lichens, berries, and seeds, and by using the snow as shelter. Hiding in the snow protects them not only from the cold weather, but also from dangerous predators like the Arctic fox, the snowy owl, and the ermine. Indeed, many Arctic animals rely on lemmings as a source of food. Research has indicated a relationship between the population of lemmings and Arctic predators. So without lemmings, other animals would surely be in trouble!"
