How good can an Arctic fox smell?

An Arctic fox has an exceptional sense of smell, which is crucial for locating prey under the snow, such as lemmings. Their olfactory capabilities allow them to detect scents from up to a mile away, helping them find food in harsh, icy environments. This keen sense of smell also aids in navigating their habitat and avoiding predators. Overall, their ability to smell is finely tuned to their survival needs in the Arctic ecosystem.
