Reindeer: A Fun and Educational Book for Kids with Amazing Facts and Pictures ¿The northern hemisphere's tundra, boreal woods, and hilly regions are home to the reindeer, sometimes known as caribou, a species of deer. They have various distinctive morphological and behavioral traits that enable them to survive in extreme temperatures, and they are well adapted to surviving in cold habitats. The unique antlers of reindeer, which are typically only found on males, are well known (although some females also have them). They compete for mate rights and hunt for food, among other things, with their antlers. Wide hooves are another characteristic of reindeer, which enable them to go across soft ground and deep snow. Since ancient times, mankind have tamed reindeer, particularly the indigenous populations of the Arctic. They are employed as a cultural emblem, as well as for transportation, their meat, milk, and hides. Reindeer are crucial to many indigenous societies' ceremonial and religious practices. Also, due to their link with Santa Claus in popular culture, reindeer are frequently connected with Christmas.
