Reindeer and deer are both members of the deer family, but they have some distinct differences. Reindeer are larger and more muscular, with broader bodies, heavier antlers, and longer legs than other deer species. Reindeer also have thicker fur coats that protect them from harsh winter conditions. Reindeer are also known for their unique ability to travel long distances in snow and ice, using their hooves to dig through the snow for food. Deer are more slender and agile, with smaller antlers and thinner coats. They also have a wider range of habitats and are found on all continents except Antarctica.
