Giraffes have horns because they are used as weapons during inter-species conflicts. Male giraffes battle with other males for access to resources, such as food, water or mates. While both genders possess the horns, the horns of males lack the tufts of fur that female horns bear. This is because the fur and skin are worn off the male’s horns as they battle with other males.Know More
During battles, male giraffes swing their heads at each other, trying to get their opponent to yield and flee the area. The horns of giraffes are technically called ossicones. Ossicones begin as cartilaginous structures, however, over time, the cartilage is replaced by bone, and the horns become very hard and solid. The males of some giraffe subspecies grow a second set of ossicones directly behind the first.
