do all caribou have antlers

Yes, all male caribou, also known as reindeer, have antlers. Female caribou, on the other hand, do not have antlers. The antlers on male caribou are used for various purposes such as combat with other males, attracting females during mating season, and finding food during the winter months. The antlers also have a deep spiritual meaning for caribou, as they are seen as symbols of strength, wisdom, and fertility.
