Why do so many arctic animals change colour with the seasons?

Many Arctic animals change color with the seasons primarily for camouflage, helping them blend into their surroundings and evade predators or ambush prey. In winter, animals like the Arctic hare and snowshoe hare develop white fur to match the snow, while in summer, they often take on a brown or gray hue to blend in with the tundra landscape. This seasonal adaptation enhances their survival chances in harsh environments where visibility changes drastically with the seasons. Additionally, color changes can also play a role in thermoregulation and communication during mating seasons.
